I think since this is an anchor link it's just fine to change for
compatibility.  People are already used to slugs in fragments and
elsewhere that don't include every possible component, and I think it
would be better to produce more compatible ones over more precise ones.
The burden of the change is very small, and the benefit is much greater.
