I think you might be little bit confused about what is going on here.
First of all, no such thing as "tag modifiers" similar to :addr exists as
you imply.
Some tags in the past have indeed been made as if they act as a "function",
and take some parameter, for example:
_HAMMYTOKENS(N)_ the N most significant hammy tokens (default, 5)
_TESTS(,)_ tests hit separated by "," (or other separator)
_HEADER(NAME)_ includes the value of a message header. value is the same
as is found for header rules (see elsewhere in this doc)
All the :addr :name modifiers you refer to, are specific to HEADER RULE
SELECTOR ($pms->get) and have absolutely nothing to do with tags.
Proposing that all tags could accept a generic modifier is a completely
separate issue and the format would need to be specified.
