I mean... no, it's not that bad. Working around retained-mode UI patterns in declarative UI is a fairly well explored problem. The real issue, in my opinion - as someone who's worked in a litany of UI systems and built my own UI frameworks and libraries: it's a lot of frankly boring as shit work that everyone gets into and then drops like a rock once the dopamine rush of implementing basic widgets wears off.
