Like this I still can not enter the wallet name as receiver in any wallet client.
I have to use additionl software and set up. That makes things more complicated, not easier.
And if you add such a feature into bitcoin directly it makes its code more bloated, making it more difficult for developers to re-implement, and also making wallet development harder. Adding the same feature on top of bitcoin layer only makes wallet development harder. In any case if such a feature is so important to you, you will use a wallet that supports it, with any shortcomings it might have but you can live with.
