Well, it would be invisible and the only side-effect be 1 extra byte
of allocated memory, and the ability to pass message data to printf
safely if it's character data...

Nope, this idea is for received messages, not sent messages.
I've been playing with this in ZFL blobs and it's really quite nice.
It lets you treat strings as character sequences without terminating
The alternative (as in Naveen's example case) is to either send an
extra null (which is not portable) or else copy the string on
reception (which is extra work)...
