It does exert some pressure, but mostly to ensure that when a user 
searches for a "symbol" that they see in a buffer, it should have an 
explicit or an implicit tag match.

Whether qualified tag names are included in the completion, and whether 
one can search for a qualified tag name reliably, that hasn't changed 
between find-tag and xref-find-definitions.

I'm not disputing that.
