Just the same, Monks and Martial Arts will forever be affiliated to the Pandaren, but are not exclusive to one race. Same with Death Knights being affiliated with Undead, but are open to other classes through unique lore and customization options too.
If a Tinker is some kind of specialist, then there's really no mutual exclusivity to midget races. This is even more the case when we have Lightforged Warframes and an entire expansion centering on Iron Horde tech showing us how Tech is used by other races. Heck, even Dark Iron Dwarves have Mole Machines as a racial!
