I think it is not so much "and", but "or".  Either we strive to make
the POS as transparent as possible, or it is up to the application.
If there is significant labor on the part of the application, a
programmer might as well use pathnames and do object archiving by

The result of a transparent POS in LispOS should be that programs
written for LispOS have very minimal responsibilities
w.r.t. persistence.

If there is not a better and easier LispOS way, then what is the point
of using LispOS?  Sure, if someone wants to go out of their way to use
antiquated and gratuitous features for the sake of portability, they
can do that.
