Maybe it is a bit meh... I did the MR to remove SCons and it's smaller
that I thought it would be:

https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/3955

but it bothers me how we keep not making a decision on this. If we'd
said, "let's keep it and support it", that would something. But
whenever it comes up, Dylan maybe fixes something on the windows
build, we talk about trying to switch Windows to meson and then...
nothing.

Also, we've had this unfortunate split between Linux and Windows build
systems where autotools suck on Windows and nobody on Unix ever had a
reason to use SCons.  With meson we've picked something that's a
legitimate improvement on both sides, get's us back to one build
system and done more than due dilligence to make it work on Windows
and we're not taking the last step because... meh?
