These are widely-used industry terms that have been used for decades. If that was a problem, surely we would have seen it by now?

Replacing terms - that have been around so long that many systems' behaviors map to them closely - with new terms that don't quite overlap seems wildly more likely to create ambiguity and confusion.

Unfortunately that is no obstacle for some - see for example the misguided efforts to replace "master/slave" or "blacklist/whitelist". Those terms are similarly clear and not problematic, but there are people who are insistent that they must be replaced.
