I don't understand your point.
I am just proposing to allow some apps to explicitly include the shim
for their convenience in case they are fully based on DPDK and
understand the risk of conflict with some other code.

Agreed - there’s no harm in doing so.

My point was simply that for a non-trivial application I suspect it will
have limited value due to the sorts of conflicts that are likely to arise.

Nick
