Having thought about it, the only situation I can think of where what
you describe might possibly present a problem is when opening an
interpolated raw file that was saved as "raw color" and hence doesn't
have an embedded profile, or where the embedded profile is a camera
profile, and perhaps the person wants to apply several other camera
profiles in turn, before deciding which one to use.

Among people who profile their own camera, choosing which of several
camera profiles to use with a given interpolated-but-still-raw-color
image is not uncommon, which means applying each profile in turn
before deciding which one to use.

Also consider if the person is testing a new profiling procedure, or
in the process of creating a new camera profile (conceptually
distinguishable, even if the same steps get used). In either case, one
might want to "apply, export, apply, export, etc" for further
comparisons of the resulting colors/tonality.

Does the envisioned way Gimp should eventually work compatible with
applying several camera profiles before deciding which one to use?
And/or with "apply/export/apply new/export/etc" when testing camera
