In preparation for the deprecation of `stdenv.isX`.
These shorthands are not conducive to cross-compilation because they
hide the platforms.
Darwin might get cross-compilation for which the continued usage of `stdenv.isDarwin` will get in the way
One example of why this is bad and especially affects compiler packages
https://www.github.com/NixOS/nixpkgs/pull/343059
There are too many files to go through manually but a treewide should
get users thinking when they see a `hostPlatform.isX` in a place where it
doesn't make sense.

I’ve sadly become aware that Aluísio Augusto Silva Gonçalves
(@AluisioASG), a contributor to Nixpkgs until 2021, tragically
[passed away that year] at the age of only 25 from complications
caused by COVID‐19.

It doesn’t feel respectful of this loss to have a bot ping his
account every time Iosevka gets an update, or to have people expect
reviews or support for the packages he maintained, so let’s retire
his maintainer list entry.
I’ll adopt ffmpeg-python in my concurrent pull request, but there are
a lot of other packages that could use new maintainers. I encourage
people to consider continuing his work on Nixpkgs if any of them are
of interest.
On the off chance that any of his family or friends ever see this
message, I wish I could say more than that I’m sorry for your loss.
