Stripping versions sounds good to me. For alternatives I'd either
split them out as separate triggers (if we want to trigger tests on
alternative changes too), or just ignore them completely (if we don't
want the extra test runs).

I'd say, if debian/control already has that field, dpkg-source
shouldn't touch it at all. That way you can avoid unnecessary reverse
dependency runs if the maintainer decides so?

OK, agreed. So putting that together, how about:
XS-Autopkgtest-Triggers: foo, bar, baz
which gets the union of all test depends, minus @, without versions,
and with alternatives either expanded or ignored?
