I think this is perfectly reasonable given the size of the codebase.

In February 2017, Windows XP made up 8.4% of the Firefox userbase. After
this there are no metrics on how many Firefox users there are, or Vista
users, I guess because those OS are no longer supported. It's also not
clear where these users are located and what was preventing them from
upgrading.

https://data.firefox.com/dashboard/hardware

Tor Metrics does not have per-version data on Windows users, only
Windows vs. Mac vs. Linux.

I think that if there was a strong desire to have Windows XP/Vista
support for Tor Browser though, it would need to have that support
reintroduced in Firefox.

Thanks,
Iain.
