Ignition laws are really dumb. My first inline, a Traditions, came with plugs for caps, musket caps, AND 209s. It shot the same with all so I don't see how this does anything. Heck, I'm sure someone could come up with a modified breechplug to shoot #11s in an Omega if they wanted to...thread a nipple into the plug and put a steel "hat" over the cap for the pin to strike. It'd probably work fine.
