It's like I said, it will be fine actually because there are still many who use electrum but with my laziness, especially for electrum, which is just copying the existing seed, I am sometimes lazy to rewrite it and that is indeed one of the main problems I have.
As for this, I am a little more intentional because this must at least be written so that we do not lose our seeds.
What you wrote here is not too clear to me, but take note that backing up on your seed phrase on paper takes the same process in a software wallet as in a hardware wallet, you must have a back up of your seed phrase written down and stored in more than one location. What do you mean by "copying the existing seed"? The seed phrase in either an Electrum software wallet or a recommended hardware wallet isn't pre-generated, it will be generated as you set up the wallet.
