Well security questions aside, I have seen this used on routers
to ensure certain traffic (e.g., VOIP) get preferential treatment
when it comes to transmission.

Of course some of these routers setup custom qdiscs so they wouldn't
be affected, but there may be ones out there relying on the default

Now I understand that having a pfifo is an anathema to multi-queue TX
by definition.  However, even if we couldn't preserve the full
semantics by default, if we could at least preserve the ordering
within each queue it would still be a plus.
