But it is easier and faster and uses less memory to simply have the
string already prepared to be sent out, no?

In Reva (et al) there's no need to allocate/copy/deallocate the string
specifically in order to send it over the FFI.

Besides those advantages, it is also one less thing the programmer needs
to consider, one place fewer for a bug to occur.  And it only costs one
byte extra per string.
