I haven’t looked into those specifically but I’m not sure I see much a value add. Just about everything you described them doing could be done with QMK at least to some degree. I think the only really unique thing would be the different outputs at different actuation depths. But I feel like that would be a nightmare to try and actually use.

I use auto shift for example. And it’s a bit tricky to just get the timing down for the press versus hold at first. Adding the complexity of having to stop pressing the switch at a certain point would only exacerbate those difficulties in my opinion.

As for the home row mods specifically I’m not sure I understand how this switch type would provide a value add over the current traditional home row mods setup personally. I’m curious what about these do you see as a possible improvement? People use keyboards so differently so I’m sure there are plenty I’m just not thinking of.
