Yes, but that argument can be made against TOTP too.
SMS 2FA is less secure than TOTP, but still better than no second factor, since most criminals with access to a password database aren't able to take over your phone number (on a large scale).
With most services allowing some kind of password reset over SMS, I also prefer no 2FA over SMS 2FA. I already lost an account because I changed my number.
A default group name, which can be changed individually would be great.
