Hi,
I hope you have calmed down by now. *Pushing over a glass of whisky*
I totally agree with this. I kind of get what they tried to achieve here but unfortunately that didn’t work. But I think other editors get their default configuration very very wrong too. Why do I need to enable basic features? I am looking at you - nano.

This patch brutally overwrites the default vimrc file located at /usr/share/vim/vim81/defaults.vim (at the time of writing) in order to tell Vim it must not indent Python scripts with spaces.
Since we have agreed on indenting Python scripts with tabs (the PEP8 standard does not give a very plausible explanation why spaces are better than tabs, anyway - but hey, those are the experts [tm], and who are we to question their decisions?!), the auto-indention of Vim has been an ongoing nuisance:
Instead of even trying to be smart and checking the indention type of the source code lines before, it just expands tabs to spaces by default, rendering Python scripts with tabulators as indention unusable as soon as any additional line is inserted. Ultimately, using nano as a quick workaround "solved" the problem, but makes developing a pain in the ass deluxe.
Vim is probably the most arrogant and ignorant editor ever written. It is even worse than proprietary/commercial products such as IDEs by M$, and that's saying something.
Erm. Have you met Emacs?
(I mean, if a user is pressing a certain key on his/her/its keyboard, who could have _thought_ of the possibility that this user actually _wanted_ to consciously press this key and have its output on the screen. Assisted programming comes to mind; using computers as tools is one thing, letting them do the thinking is another... :-/ )
Of course, one could disable expanding tabs into spaces by setting up a custom ~/.vimrc file, but this causes Vim to ignore _any_ other directives as well, which means there is no syntax highlighting anymore, matching brackets are not marked as such, and we are basically sitting in front of an machine behaving like one of its colleagues in the 80s.
Some smart people came up with the idea of system-wide files such as /etc/ssh/ssh_config, or /etc/vim/vimrc, respectively. It even contains statements for including a _custom_ vimrc at /etc/vim/vimrc.local, which is exactly what we want to do.
However, Vim reads its configuration from /usr/share/vim/vimrc, which is not simply a symlink to /etc/vim/vimrc or vice versa (that would be too easy, wouldn't it - why not spreading the same content twice across a system to bloat up things a little bit, eh?), and jumps into a Debian-specific configuration file afterwards.
As soon as any custom directive is placed in /etc/vim/vimrc.local and Vim is told not to overwrite it, we are dealing with the same less-than-default configuration mentioned above.
This leaves us with the decision of (a) either copying the entire content of /usr/share/vim/vim81/defaults.vim to _every_ users home directory, creating boiler plate configuration en masse or (b) tamper with files managed by the systems' packaging tool, which means we are damaging the integrity of our machines (did anyone mentioned security here?!), for nothing except a simple change to the Python indention plugin behaviour at all.
In the authors opinion, (b) is the least unfavourable option. This patch finally "solves" the unwanted Vim behaviour on our machines, hopefully making Michaels and my lives a little bit less harassed, since we need to puke into one less front yard of another development team all the time.
I am looking for anything to get my blood pressure down these days…
Keep them coming, those fixes for the problems of my life.
