But my point is, what is the compelling reason to change now?


Does there have to be a compelling reason? Criteria for identifiers have
been established, many identifiers are being changed because they don't fit
the criteria. I think that's all there is to it.



Some non collocated VORs have had their ID changed from the
same as the nearby airport (e.g. Williamsport, Pa), some have not
(e.g. Manchester, Nh; Pottstown, Pa).


Yes, I believe I mentioned that. It appears the VORs that are fairly close
to the airports have been left alone while those that are further away have
been changed. The cutoff appears to be five miles.



Perhaps the relatively recent K prefix for lower 48 airports has
rendered the changes unnecessary.


There's nothing recent about that K.
