Is Multi-Seag a Necessity?

I see and as I understand there's also some development and discussion around changing the density of that QR code so I presume that instead means if you have it as a lower density QR it just needs to do more different QRs in a in GIF format or something similar to that. One other thing I've seen is general ongoing debates in the community online discussion people saying oh no don't push people into multi-seag it's too complicated. How would you advise somebody to whether they are deciding on just single signature with a passphrase versus actually take the time learn to domulti-seag sure?
