Please refrain from hyperbole, it has nothing to do with my eyes or
"moral corruption". More seriously, I have mentioned this already: wm4
said it is a worthy goal.

wm4, being a lead of mpv (a main client of FFmpeg), is someone whose
opinion I take seriously and think hard about, even if I don't agree
with it personally in some cases. Many things I did in the past were
not liked by many here, and are still not liked by many going by
recent IRC logs. I wanted to find a common ground, and here was
something where I actually agreed with wm4 even from my own
Again, this goes back to what I said: I do things not because I find
it interesting, but because someone whose needs are more than mine
benefits from it.

More generally, I find something very inconsistent here: table
generation is claimed to not be "speed-critical", yet there are a few
people here who still think it is "critical enough" to justify
retaining hardcoded tables, and the associated complexity of the
configure/build system.
