Ah, okay, now I understand. I don't know if it helps with your
problem, but are you aware, that "pool" also supports global pools, by
naming the pool? pool names also are settable, so you may already have
the settable [value] in [pool] - and then some.

I can see your motivation, but my usual caveat applies here as well:
You would create two incompatible Pd version with doing that as an
internal: MSP Pd and CVS-Pd. I don't think it's a good idea, in fact
I'm convinced, doing this is a bad idea and would make all hell break
loose. ;)

I'm not really into the depths of the Pd source, but couldn't this
create similar problems as settable sends/receives create? Also you
could work with abstractions and pass the $0 from the parent patch as
a creation argument. I do this extensively in RRADical to create
somehow-non-local-but-still-not-totally-global variables.

Not if you consider my above caveat to be true and want to keep patch
