I think so. The toolbar buttons and the scrollbar handle are simply 
smaller, and a lot of hardcore users disable them anyway.

The font size or rendering quality don't seem to be affected by the 
scaling factor.

Still, some users won't like it, or will simply be confused if they have 
to hunt for "GDK_SCALE=1 emacs" in the PROBLEMS file, so we have to fix 
that sooner a later, too. But it seems to be a separate bug, not one 
we've already seen reported. And, judging from the past bug reports, 
problems like this are relatively easy to fix.
