Problems with child components during upgrade from Livewire 2 to 3

I am currently trying to upgrade our sizable application from Livewire 2 to 3, but I am getting increasingly frustrated with Livewire 3. On almost all the components containing child components, the error about component missing or snapshot of component missing pops up. I understand that the solution to this is to add wire:key attributes, but this seems to only work when all the DOM elements get one, meaning every single DOM element up to the root component needs a wire:key, which is extremely tedious. Are we missing something? I can't help but feel we are doing something else wrong entirely.
