So, I'd say it is correct to summarize it as "it is quite pointless
currently but could be used to improve things in the future"...

What I don't like about it is that it will only work with X11 and that
is what almost all developers use.
Nowadays except for xv they all use the same code, while that is far
more ugly at least it is the same for all platforms, ensuring it is well
Still, moving it to x11_common is better than what we have now, so I'd
welcome it if someone does that.
