Not completely arbitrary, but yeah, most common stuff is
actually supported.

Anyway, I'd rather avoid pulling in such (under the hood) complex features,
and their actual issue would be rather solved with the planned terminal based
user interface (TUI).

Further, this may not be to friendly for people with color-sight impairments,
the default GTK theme is normally already designed with accessibility in mind,
changing styling may break assumptions baked in there.

Also, as Stoiko mentioned, the button class is used in more places than just
the obvious ones, so more subtle breakage/weirdness can happen.

Focused buttons are already highlighted, and the Alt+<underlined-key> helper
is available too for keyboard only installations, as documented in:
https://pve.proxmox.com/pve-docs/chapter-pve-installation.html#installation_installer

So no, I do not want to include such styling patches.
