Since new functions are similar to `replace-match', I think they
should also have similar names, e.g. `replace-match-string' or
`replace-match-as-string' meaning that it returns the replacement
as a string. Also I think it should have exactly the same arguments
as `replace-match'. And one function should be enough - there is no need
for -no-properties function because properties can be easily stripped
on the returned string when needed.

I think there should be an option that will enable such understandable
replacements in the prompt (but not for multi-line replacements).
