If the hold isn't issued and things don't go as expected and comm is lost,
then you have an airplane coming in the airspace unwanted, but at a known
and predictable time since you are tracking it on radar.


Not issuing the hold was not part of any scenario.



If the hold is issued with no EFC and comm is lost during the hold, then
you have an airplane which will enter the airspace at an unknown time.


Say what? If your comm was still operating prior to reaching your clearance
limit without an EFC why didn't you query the controller?



Hopefully, the pilot knows enough to wait until the ETA, but what if he
doesn't? Or what if his watch is 5 minutes off?


Hopefully the pilot will know the controller is unlikely to have his ETA and
will just fly the approach without holding at all.
