So one could take a strict view that "no PL/Java function should
ever be marked IMMUTABLE" because every one depends on fetching
something (once, at least).

The failure to find and execute the function code itself is not a failure mode that these markers need be concerned with.  Assuming one can execute the function an immutable function will give the same answer for the same input for all time.
