With the path they've chosen, it may mean less version churn, but the other side is you've gotta wait for each widget author to upgrade their widgets when Ratatui upgrades. This can lead to a situation where some widgets upgrade, some don't, and you're left either on the lower version with unpatched issues, or the newer version missing widgets.
I much prefer the design of web-sys and js-sys, where all the features are included and gated behind feature flags.
