I am fine with it if we want to follow what is retained in the IEEE 1588g,
but I still think this word is not that helpful on describing its role.

I think then you better define "*Grandmaster Clusters*" in the terminology
section of this draft or use reference to IEEE specification. And "NOT
ALLOWED" is not defined as normative text in RFC 2119, hence you would need
to use MUST NOT or NOT RECOMMENDED depending on what you exactly want to
express.
