If my search skills are right, the last model with a PowerPC processor
was the Power Mac G5, with the latest revision released in late 2005.
That's almost 14 years ago (on October 19, if Wikipedia is correct).
What do you think would be a reasonable time frame to eliminate support
for old hardware? From my perspective, it's always a trade-off between
developer time and supporting users.
In my opinion, we could eliminate PowerPC support if it were broken. Unless
some PowerPC user wants to step up and do the maintenance, I wouldn't be
concerned about removing it. One of the theories of GUB is that the developer
time in minimized for maintaining cross-platform build. But as we can see, the
theory doesn't always match the practice.
But if it's not broken, I see no reason to remove it. As long as the developer
time is zero, we should leave it.

supporting macOS users via the GUB distributions. Again, no reason to
eliminate -x86 just because the latest version of OS X doesn't support it.
Many people (including me) have refused to update to 10.15 precisely because it
breaks existing software that works well for me.

That matches my understanding.
Thanks,
