This was touched on in the discussion, and I think there were explicit conversions
in early drafts.

One can of course add string->mstring as a synonym for (1-argument) string-copy, but it's not clear
to be that would be better.

string->istring can be expressed using substring as well as string-repeat.
I'm ambivalent about adding an explicit string->istring - I'm not opposed.

At the very least "Conversions" section should explicitly mention (as a post-finalization
editorial change?) the recommended idioms for converting to istring or mstring.
