I think the thread hasn't seen an answer to the question of when these
are actually used or useful, as asked in another subthread as well.

Would it be possible to have this in a separate package? Of course then
with a temporary compatibility PDEPEND on it with udev[extras] until
packages needing gudev migrate over.
And what of the above listed other things besides core udev does gudev
require or potentially use?

On some non-desktop systems perhaps, yes.
