I imagine that level of criticism must be demoralizing. (That's why I didn't pile on, though I've been vocal about accessibility on similar threads about other toolkits.)

Just so I can understand where you're coming from, what's your motivation for developing yet another custom toolkit, despite all the challenges and all the table-stakes requirements that haven't yet been met? There must be some reason you feel this is a worthwhile use of your time, but I don't understand what it is.
