Debian has stopped supporting x86 32bits recently, Chrome did so 9 years or so ago.
We've carefully ran some numbers before doing this, and this affects a few hundreds to a few thousand people (hard to say, ballpark), and most of those people are on 64bits CPUs, but are using a 32bits Firefox or 32bits userspace.
The comparatively high ratio of 32bits users on Windows is not naively applicable to the Linux Desktop population, that has migrated ages ago.
