Since they changed from a non-ICAO id (i.e. one containing digits) to an

they picked that particular id, PJC, maybe it's just the best of the
remaining ids?

As far as i can tell KZEL is available, or KZMA, or ... but who
knows. PJC just seems completely random - I can't figure out a person
or place to connect it to.

According to http://www.skygod.com/asstd/abc.html "Z" codes have been
reserved for "special uses".
Along with the dirth of ids there are also apparently restrictions
such as "the first and second letters or second and third letters of
an identifier may not be duplicated with less than 200 nautical miles
separation." Ids like PJC maybe what you end up with in that
situation.
