@JAnD until there's a technical solution for your feature request, you might want to ask for Abuse filter helper permissions on meta:SRG. Local admins helping with false positives of global filters are a major use case of this user group.

On Google Docs where I maintain GAF 365's code, I've adjusted that code to prevent any more false positives, and I'm not commenting any more about the global filter without spilling any beans.

Other users who can view or edit private filters on their home wikis can also request GAFH on SRGP as well.

Errm, are you implying that you manage some code in a Google Docs document?

Abuse filter syntax code and regex of a private global filter, to be exact.

I don't see anything in here that would require code in MediaWiki-extensions-CentralAuth?

And this should probably be discussed somewhere on-wiki before being implemented, as private global filters are private for a reason and I'm not certain we want to let any admin on any tiny wiki to view all of them.

Yeah, agreed. That was a reflexive move from a third party extension implementing global user rights to the extension that actually implements global user rights on Wikimedia wikis, without thinking about whether that was actually needed.

On the other hand, why should some private filter block work for local admins?
Private filters are because of vandals (eg. blacklisted words) and local admins (or othe local group) should be allowed to override them.
