Swapping [2] for [HDPMI32] DOS32/A, WDOSX, CWSDPR0 (DOSX)

I wonder whether there is a possibility (whether there is a residual theoretical risk) of host-internal swapping with a DPMI host running applications in Ring0.

All known Ring0 hosts (DOS32/A, WDOSX, CWSDPR0) don't swap - it this just coincidence or is there a fundamendal "problem" preventing Ring0 hosts from swapping ?

what do you mean? Of course there is NO "fundamendal problem" with swapping for apps running in ring 0.
