Author of Lustre here! Yeah I agree, lack of a robust headless component library like radix-ui or react-aria is such a mark against Elm. I think it's even more important for Lustre because really all our users are going to be backendy folks with little interest in the nitty gritty frontend stuff.
Lustre will eventually have a companion ui library to plug this gap but it turns out maintaining all this stuff is a bit of a time sink, so I'm taking baby steps ^.^
