Allowed for what?

I think ABNF authors expect to be able to use these.
 
I don’t want to have newlines in most of my identifiers, which generally are one data type for which I need to set the repertoire.

Well, then you don't need this document. But Section 2.2 covers this well enough.
https://datatracker.ietf.org/doc/html/draft-bray-unichars-13#section-2.2

Maybe the PRECIS IdentiferClass is a better fit?
 

Before making these repertoire decisions, you first need to say what kind of text you want to describe:

I don't agree with your categories here.

Surely the YANG example is good enough. Identifiers:
https://datatracker.ietf.org/doc/html/rfc7950#section-6.2

and then, as linked before, human readable text:
https://datatracker.ietf.org/doc/html/rfc7950#section-9.4

So, "Unicode Assignables" can appear in a more restricted container easily enough.

Yes, but the repertoire of the protocol includes FF now,

Yes, I believe that I just wrote that these productions don't have to cover the whole protocol. 
 
(You ABNF is problematic, because your pages will be very short [...]

Yes, I will not win awards for that one :), I just dashed it off to make the point.
