Yes.

Yes, but that would break too much code. I think the right thing
to do is to leave Scheme's mutable strings pretty much as is, but
to add immutable strings as a separate layer, overloading the R5RS
string operations that don't have side effects (e.g. STRING-LENGTH,
STRING-REF) to work on both immutable and mutable strings (as they
already do, thanks to the immutability of literal strings).
