> Web Components have too many mechanics and assumptions backed in, rendering them unusable for anything slightly complex.

Does not line up with my experience (the past 8 years or so of working with native web components, Polymr and the Lit library) at all. You can build staggeringly complex views using nothing but web components, I’ve done it, I am doing it, and inshallah I will keep doing it.

What in particular do you believe web components are unusable for? What do you count as crossing the line into ‘slight complexity?’
