They are. $ git add . $ git commit -m 'fixing #23'

the ability to write a commit with a number in it doesn't magically create a distributed issue system which is still hosted in ONE place, which is still down when ONE place is down, and which still demands you have an account registered in ONE provider where those issues are posted and discussed.

btw the auto-linking auto-fixing commit syntax is just a local convention, which isn't even compatible between the 2 biggest players, see https://github.com/zzzeek/alembic/ and https://bitbucket.org/zzzeek/alembic/commits/all for example reference.
