how come using your mobile wallet with your bitcoin full node is still difficult?

you gotta install the right version of electrum personal server that’s still maintained or else go for blockbook. 

really cumbersome. wish bitcoin core could add the extra indexing as an opt-in feature, so then you can scan a qr code with your phone and connect. 

 you don’t need electrum 

 what then, neutrino? 

 bitcoin core tracks all of your utxos via descriptors, why would you need an index ?
