As hardware acceleration for AES is emerging (Fireinfo indicates 30.98% of reporting installations support this, compared to 28.22% in summer), there is no more reason to manually prefer Chacha20/Poly1305 over it.
Further, overall performance is expected to increase as server CPUs usually come with AES-NI today, where Chacha/Poly would be an unnecessary bottleneck. Small systems without AES-NI, however, compute Chacha/Poly measurable, but not significantly faster, so there only was a small advantage of this.
This patch changes the OpenSSL default ciphersuite to:

I would like to highlight that practically all mobile phones have AES-NI as well and that we do not have any applications here which have very heavy encryption load where this could not be changed to something that would suit the used hardware better.
