Comment(by marshall.perrin@…):

 Good question! I only assumed there must be some reason not to do it all
 the time, because otherwise why had the patch in #22954 from almost two
 years ago never been applied onto the official portfile?  Someone went to
 the trouble of explicitly adding --disable-corefoundation to the tcl
 portfile back in the past and I don't want to second guess other folks'
 use cases.

 But certainly from my own perspective I'd say enable it all the time, yes.
