Yes, this is expected.  Tags are refs, and when you specify no refspec,
you're asking for the default behaviour, which usually involves fetching
tags.  But when you specify a refspec, you are saying, "I want you to
fetch this, and only this; don't fetch anything else."

For example, if I say, `git fetch origin
refs/heads/main:refs/heads/main`, it would be very unexpected for it to
fetch tags as well; I only wanted it to fetch the main branch.  In fact,
I might be explicitly relying on it not affecting any other refs.

If you want tags nonetheless, you can use the `--tags` option, which
should fetch tags in addition to the refspec provided.
