No, I never thought that. It's why I used Silence instead which did (and technically still does, even those development for it is dead) SMS encryption.

People were calling for Signal to do SMS encryption for ages (for the above mentioned lack of data) but Signal refused to implement it. Hence why Silence was started.

Thankfully data is a little better now in some places but still doesn't change the fact that for some, SMS is the only practical means of communication and they deserve E2EE as much as anyone else, even if it doesn't completely protect them.
