It's a good idea, however this  particular way of doing it is not
practical -- because in many cases, the majority of images opened do
not have a profile. We need to find an approach that would not require
vast amounts of dialog interaction.

In any case, profiles are NOT automatically attached to images without
profiles, in my tests with PNGs. The reason you might assume they are,
is that GIMP automatically displays images which have no profile
attached, as if they had the working profile attached.

If your experiences don't match the above, perhaps the specific save
plugin in question does (wrongly) attach the working profile when
saving.
