I agree. There is a big difference between being able to merge RDF
graphs and merge OWL "Things". I use owl:sameAs to do the former when
the properties are all going to be relevant to both, but the two URI's
still don't necessarily match a given whole-world OWL structure.
rdfs:seeAlso has never been a big attraction to me due to its lack of
actually saying anything about what you are going to get, possibly due
to its colloquial use with FOAF and sending you off to a random foaf
file for more information about an, as yet unnamed, entity.

Given that you are never sure how someone is going to utilise your OWL
structures in future you cannot be held accountable for every
statement you make retrospectively, particularly if the dependent
vocabularies (or the assumptions of the person utilising the
vocabulary) are the cause of the breakage.
