That's not quite true: there is "String.make", which does what you want.

Yes, it's hard to do this with the current standard library.  The question
is: who needs these functions anyway?  I can't remember ever having felt
a need for them.

I beg your pardon - what else do you have in mind???

The point of the standard library is not to have a function for every
imaginable problem but to have ones that cover standard problems.

Things are not half as bad as you describe them here.  There may be
cases where C is more productive - because you happen to have a library
function for the problem.  But even in this case you can just interface
to C, which is really not that difficult.

There are surely cases where the OCaml standard library lacks generally
useful functionality, but it's usually good enough for most problems.
