Grant field access to (last) login field, required for views

Would this also work for the "last access" field?

I doubt that we should do this. This module has been stable for several years. We decided to grant access to those 3 specific fields, but not to others (e.g. status or init). If we change it now then it would affect all sites, and some of them might not want it. If any site wants to change the default then they can use the hook just as you wrote it.
