I guess that in this day and age the pipe community is just too small and therefore the powers that be aren't worried what we think.
You nailed it right there in more ways than one. From what I've heard, the deeming regulations have little to do with pipe tobacco or tobacco itself: they're an attempt to clamp down on the vaping/tobacco free smoking products. Hence (again, from what I've heard), Big Tobacco is either in favour or actively furthering these deeming regulations: they want to if not destroy, at least greatly curtail the competition they're getting from tobacco-free smoking products.
Pipe tobacco is a negligible demographic in the whole tobacco market, and thus is just lumped in along with the rest. We're a side casualty, not the target.
Of course, said regulations are just one more weapon in the WHO's war against smoking. Whatever helps them win it, and whatever helps them meet their deadline for the eradication of the 'tobacco disease' (yes, they actually call it that in official documents). In some countries the agenda is pursued through heavy taxation, in others through bans, elsewhere via regulations, &c., &c.
