YUCK! So we'd have both message and memo doing basically the samething, with different interfaces.

If it’s the API difference you object to, it’d be OK for the two functions to have the same signature. It’s no big deal.

you've got two functions which are so close to each other, one single function 
would be better.....

If having one single function would mean changing hundreds or thousands of callers, then there is an important sense in which one single function would not be better.

NOBODY will write (message "30%-50% done")

Admittedly the example was contrived, but I thought it was cool how one can use % to delete parts of messages, something that is much worse than quote restyling. More commonly people compute a message string S somewhere else and then call (message S), and that does have real problems with %, particularly in situations where an adversary has some control over the contents of S.

It’s not intended to be “surreptitious” or “hidden” or anything like that, ....
That may be the case, but it _seems_ very much like it.  If the intention had 
actually been to be surreptitious, what more could have been done than was 
actually done?

Lots. We discussed and rejected more-“surreptitious” options back before this stuff was installed. For example, we discussed changing ‘format’ to behave like ‘format-message’ does now.
