Wasn't Tom Cargill's article published in 1994 and the STL written in
1995?

I don't understand the relevance of Tom Cargill's article. The
article provided precious little insight into how to deal with
exceptions. It describes a bunch of problems, and then, essentially,
throws up its hands. Cargill certainly doesn't suggest that any
problems could be solved by changing the pop() interface. Many people
have read that article to mean that it might not be possible to write
exception-safe code at all, and the STL was initially written with no
regard given to exception safety. Exception safety for the STL, as I
wrote, came later.
