No, this won't work with const storage. You won't be able to use it in
non-writable memory and such strings won't be placed in const sections
of the executable and therefore won't be shared between processes.

Yes, since you have the buffer size for the terminating zero anyway,
maintaining the terminating zero on string modification is the way to go.
