IIUC that's an issue with the linter or perhaps the implementation of
short input lists in general.  I've CC'd Ludo as he is the one who
allowed us to write inputs (list bash sed ...) in the first place,
perhaps he knows what to do here.  We probably ought to convert this to
short-style inputs anyway.

Note, libhandy 0.0 only exists on master (and therefore core-updates),
because there are packages still using it.  If there's no more users
post updating gnome-tweaks, it is to be removed!

Nice catch, I think this was previously done by a different phase. 
However...

Please note the phase and perhaps change its name to reflect what it
does.

I'm not sure this is the correct move here.  Python uses GI at runtime,
not natively during build.  If gnome-tweaks requires GI at build time,
it's to be added as both inputs.

Split the long line.  Also perhaps add a comment in the file itself as
to why this is needed if it's not already obvious from best practises
in core-updates-frozen.

This should probably done first, particularly if it helps avoid the
linter complaints you encounter.

In my personal opinion, 1, 3, 4 and 5 could also be done in a single
commit, though YMMV.  Also, I'm not active on core-updates-frozen, so
take everything I said as lexical analysis at best and with sufficient
amounts of salt.

Cheers,
