Exact same experience here. Tried porting a huge react code base (over 22kloc) to WC/litelement, and it wasn't easy finding a 1-1 replacement (even with libraries) for stuff like multi-layer conditional validation etc.
Will wait for part2 to see the solution because I do agree with some of this ranting. Hopefully this doesn't stop with part1.
I don't have this series planed out but I never wanted to say that they are an easy replacement.
What I wanted to say is that it would benefit the community because everybody would have on target and one common pattern on writing them.
