Transferring wallet address labels from different wallets is non-trivial today, as there is no standard for this metadata it seems. 

- Could address labelling be included in wallet config files at export? 
- Could wallet descriptors help in the future? 
- Is there any best practices today or wallet recommended for this? 

The goal is to keep a clean and updated state of wallet addresses labeling for easy coin control and good privacy, while not being locked in with a wallet that does not let a user export their labels. Thanks a bunch!
