Off the top of my head (testing on XFCE, because that's all I'll have
for the coming week):
- with Firefox, as in special-mode-map, SPC scrolls forward and S-SPC
scrolls backward,
- in Libreoffice Calc, SPC self-inserts, S-SPC selects the current row,
- XFCE's keyboard shortcut manager allows binding Shift-Space.
I don't know how much those rely on GTK+; possibly they do something
similar to Emacs's X11+GTK configuration?

Right; that was my uninformed conclusion so far. All my setups run X
for now, so I can keep running the X port, although I'm slightly miffed
by the fringe icons being so tiny on screens where I crank up DPI
scaling; afaict --with-pgtk handles this better.
I'm also idly curious about these GTK limitations; are they documented
somewhere (either Emacs-side or GTK-side)? When researching this S-SPC
issue, I tried to search for developer manuals and bug trackers, but the
only relevant results that showed up were Emacs related (that's how I
found out about the pgtk-use-im-context-on-new-connection /
pgtk-use-im-context knobs).
Thanks for your clarifications; setting aside my question on GTK
limitations, and my issue with fringe icons shrinking when increasing
DPI scaling (that would be… bug#37932, at first glance?), this can be
closed I guess?
