Re: sameAs.org milestone

A very useful resource, which touches on a current issue for me - I may be reviving a long-visited discussion here... (e.g. [1] )

Is it current practice now to use owl:sameAs for mapping ontologies, despite the semantic implications of sameAs? Is a weaker interpretation of sameAs now being taken? 

My understanding was that alternatives to sameAs should be used unless there is absolutely no doubt that the two Things are in fact exactly the same entity. The vast amount of data in sameas.org suggests to me, though, that common practice is tending towards using (a slightly weaker interpretation of) sameAs ?
