Paging I/O uses a 4K block size, which is inefficient for FICON, unless you are
using zHPF. z/OS has
not enhanced its paging I/O to use zHPF. With non-paging I/O, you can use a
larger block size, and
many of the access methods use zHPF.

That does not require the storage to be fixed, unless you are disabled
or you are using a real address for the target of the copy.

That is correct - cross memory page faults are resolved as you would
want,
so the PGSER FIX is not needed.
Unfortunately, the system does not resolve ASTE-validity exception (PIC
2B),
which is why nonswappability is required.

No, 052 abends are issued by service routines for PCAUTH services.
VSMLOC is not a PCAUTH service. and its service routine does not
issue 052 abends.
