There's an alternative syntax proposal here which is quite similar:

There's a domain separation concern if you don't always add a tag: it no
longer becomes possible to encode strings which legitimately end with a
given postfix. This could, among other things, be exploited by an attacker
to change how strings are interpreted, provided the attacker can control
the key.

I would prefer not to have that sharp edge.
