My fear is that what you propose would require a prepress operator to
run through hundreds of info boxes, or to use some kind of preflight
app/script to sort the image files. Then the operator would have to
construct automations to handle the various profiles that you've used.
No I don't think that is very useful. I suppose in such an ad hoc
implementation it would be better than NO profile at all but I think
this would have very limited use even in closed loop workflows. The
point of the idea is to keep it transparent and seamless, but without
having to manage so many redundant profile instances.
What I'm envisioning is that a URL-based embedded profile is read
automatically (of course new software would have to support it), track
down the profile using the URL, download a single copy of it, and
associate it with all objects claiming it as the source profile. It
would be totally transparent to the user unless they didn't have an
internet connection.
Now if the internet connection is really a big stumbling block, that's
why I'd raised the idea of a subset profile. There are six tables
getting embedded with an output profile (up to six anyway), and only
one of them is really needed, the A2B1 tag (device to PCS
colorimetric). And a portion of the B2A1 tag would be helpful if the
image needed to be reseparated using black point compensation
(basically the black point information).
