@J-N-K commented on #14511:

I think the biggest improvement regarding code style and extensibility comes from the removal of the core type mapper and the refactoring to value(de)coders.

Yes, smarthomej/addons#208 will be fun to merge ;-) It somehow obsoletes the changes done in the meantime.... Will see how it fits together.

The second point I am concerned of is the UOM handling, especially as I have not much experience with it and see a huge potential to break existing installation.....
