Today I noticed, that lang/gcc13 gets post hoc registered as dependency

This is the provides/requires mechanism of pkg, which started to have
a broader effect recently. It is still somewhat WIP, see
https://reviews.freebsd.org/D49136
Thanks for your help, highly appreciated!
Why/how does that happen? (note that nothing changed between 'pkg
install gcc13' and 'pkg delete gcc13' - but gcc13 wants to doom 222
unrelated packages!)
Can you please provide an output of following commands?
pkg query %b gcc13
Please note that due to math/openblas buidlfailure, I switched to
GCC_DEFAULT=14
(https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=285140), and
interestingly, this pkg(1) issue affects gcc14 the same way.
pkg query %b gcc14

'pkg query %B findutils':

Matching $gcc_provided_shlibs:
NONE
The result above is just one arbitrary example out of 300 packages which
would be removed by 'pkg delete gcc14'.
0 out of 300 packages share any gcc14 provided shared library.
I hope I correctly understood what the requested query results are about.
This is the corresponding q'n'd script:
#!/usr/bin/env sh
IFS=$'\n'
GCC_PKG_NAME=gcc14
gcc_provided_shlibs="$(command pkg query %b $GCC_PKG_NAME)"
for unrelated_pkg in $(command pkg delete -n $GCC_PKG_NAME | sed -n -E
's/^[[:blank:]]+([[:graph:]]+):[[:blank:]][[:digit:]].*/\1/p'); do
echo "To be deleted: $unrelated_pkg "
echo " 'pkg query %B $unrelated_pkg':"
for _utilized_shlib in $(command pkg query %B $unrelated_pkg); do
echo " $_utilized_shlib"
match="$(echo -n "${gcc_provided_shlibs}" | command grep -F
$_utilized_shlib)"
done
echo " Matching \$gcc_provided_shlibs:"
line=''
for line in $match; do
echo " $line"
done
[ -z "$line" ] && echo " NONE" || read void
done
