I'm not sure exactly what you're referring to. Do you mean when the location isn't filled in, and you see [place of birth?], [place of death?], etc.?
I absolutely agree that anything is better than nothing in these fields. Usually at least a country is known for at least one life event! I mean, if it isn't, what sources could possibly be used for the names and dates that don't include any locations? That would make me doubt all the info given.
Also, if a location is suspected but not certain, that's what the confidence levels are for. It can easily be marked as uncertain, and then it's clear that it's not known fact, but at least it's a guideline.
