Ripping out 32 bit code to clean up the code base (and, typically,
finding bugs in the 64 bit code while doing that) is something I'm
planning for the end of 2022 or early 2023, so there's enough time left.

And just because the latest version of Cygwin doesn't run on Vista/W7/
32 bit systems anymore, doesn't mean they can't run Cygwin anymore.
Older release will still be available for a time on cygwin.com, and
more or less infinitely via Peter's time machine.
