If by "remove all" you mean "efefef" - "ef" == "", I think that's a
footgun.  Similarly for "efabcd" - "ef" == "abcdef" - "ef".

Maybe it should be "remove the first one" rather than a suffix.

Then for removal of multiple substrings, you could allow the RHS to be a
sequence of substrings:

>>> "efaxefef" - "ef"
"axefef"
>>> "efaxefef" - ["ef", "ax"]
"efef"
>>> "efaxefef" - ["ef"]*3
"ax"

BTW these are interesting ideas and I'm just exploring the possibilities.
Not proposing or agreeing with anything.
