I don't know if "more convenient" would be the words I would use. Setup on this project is very easy, it has very straightforward instructions. Meanwhile, I did a quick 5 minute pressure test of what you suggested and found myself with more questions than answers. I am not saying one way is better than the other, I am just thinking that for those that don't breathe SSH/VPN/Wireguard/Terminal Emulators/etc.. this project is actually far easier to understand.

Also, funny enough on compatibility, but "Termux" is not on iOS, so it fails that basic check. But there's alternatives, of course. Just an observation.
