IIRC we don't have an agreement on this. My personal opinion:
A new command/environment which translates 1:1 into a style may be as new as
you like (if it is officially released), as long as it is documented that this
style may not work with older TeX installations (the latter is needed so that
there is at least a chance to look up the reason of the error message you get
if you use it nevertheless).
In the course of stable releases, I'd prefer also to apply your stricter
rule here, unless there is a way around this problem using the new local
layout mechanism.
