then submit a patch and see. it took me less than 3 hours to submit patches
for the two other bugs you submitted, and you've now probably spent more
time arguing about how it will get rejected than you would've spent fixing
it in the first place.

please realise that "nobody in their right mind would do $FOO" is nothing but
an insult, directed not just at those who disagree with you but also at
those may agree with you but just hadn't seen it as a problem before.
don't expect this to improve the conversation or lead to a conclusion in
your favour.

there is such a thing of promised functionality. changing how commandline
arguments are handled can break existing scripts, causing havoc beyond the
benefit the change brings in.

and a helpful contribution would be to at least submit bugs or patches to
improve the man page. wayland developers are not the pkg-config maintainers
(afaik) so we're really just wasting time on this list discussing this back
and forth.
