I don't understand.
Which previous settings?

As far as I understand, activating a profile never _removes_ any value
from environment variables.

I gave the example of EXWM, for which the user would like to change the
profile but a subshell won't do since it won't reflect on the parent
process, Emacs.

All that said, this is just a suggestion, I can live without this feature.
