Joking aside, that's actually the highest number I know of with any device, with HomeSeer's switches and dimmers matching (and at least some others I know coming in at triple tap). There may be other classes of device that I'm not even thinking of that might fall within the realm of these capabilities, but none are coming to mind.
I once joked that Hubitat should do exactly what you suggest. Or maybe I wasn't joking--I'm never sure with this idea. 
Staff do not appear to have been moved:
(That being said, I still find Inovelli's button numbering odd on Hubitat, though I understand that pretty much anything you can do is odd. What makes it even more odd than ST is that Hubitat can do "released" events, which gives "held" a bit more meaning, IMHO, in that the former would logically follow the latter for some real-world actions, but then the latter is already usurped for another purpose. But again, no great way to do this...)
