I prefer mrCx because rm tends to confuse people not familiar with
AppArmor (no, 'rm' does not mean delete permissions ;-) but in general
you are right.
Note that this will result in two child profiles - one for each binary:
profile /usr/bin/gpg {
# whatever is needed
}
profile /usr/bin/gpgsm {
# whatever is needed
}
If you want to have a common child profile for gpg and gpgsm, use
/usr/bin/gpg mrCx -> gpg,
/usr/bin/gpgsm mrCx -> gpg,
profile gpg {
# whatever is needed
}

I didn't read all text on that page, but on a quick look it looks good.

Actually it *must* be good because it links to my presentation ;-))

In such cases, it's a good idea to open a bugreport upstream [1] or to
send a merge request on gitlab to get the abstraction updated ;-)
You might still want/need to add it in your profile as a temporary
solution until everybody has a new-enough abstraction.

Indeed, giving gpg read access to all files in ~/.gnupg/ makes sense.
I'd be very surprised if this directory contains a file gpg should not
be allowed to read ;-)

[1] actually a bugreport against the Debian AppArmor package also works.
Even if I don't use Debian, I read all AppArmor-related Debian
bugreports.
