WTH don't all icons have a strike through version

I get it - this is a longshot, but it would be great if every icon could have a strike through version. I have a few buttons where it would be ideal if the icon could have a strike through indicating ‘no’.
I get that creating every icon with a line through it would be a pain, but it would be great if a line could be added on to with CSS by appending the name with ‘st’ for example.

Home assistant largly has no say in what icons have strike through or not. HA uses this library
