Thanks for this. That would be reason enough to explain for
some of the implementations that have been around for a while.
I've heard of recent implementations that do not support global though...

Can you point to a specific phrase in the RFC where it says so?
I could not find any mention of the word global in the RFC
nor any RFC2119 words relating to scopes of addresses.
