You write as if you aren't a time traveler.
[declare] has had this behavior for at least a decade.  That's more than 
enough time for the ninjas to test and package it up to use in the manner 
described by the OP.
What is the cost of leaving a hook for functionality that has value to the community?  (I count two documented uses on the list, both geared toward 
a larger community of users.)  If the cost is old lines of code and a creator/flag, 
it should remain. If it's substantially greater than that, I'd be interested to here the technical argument for removing it.
Keep in mind there are way more obscure old code paths-- [template], for example...

Using [declare] in abstractions has never been an encouraged practice,
The 0.41 helpfile includes this warning:

'WARNING: you might want to avoid putting "declare"
statements inside abstractions, as their effects will extend
to the calling patch. As of version 0.41, "declare path" is
ignored inside abstractions, although, probably unwisely,
"-stdpath" takes effect (on the calling patch as well as the

So basically [declare] only was "allowed" in a toplevel patch.

I think it is was wise, that the confusing side effect of
[declare] "extending to the calling patch" was removed.
