Spacemobile is probably years ahead of them but you’re correct. They are most likely why the industry is not paying for this because spacemobile will work with ant smartphone woth voice, data and text.

Spacemobile will worl with any newish smart phone for full 5g functionality voice, text and data.

I would imagine this is why no one wants to pay for a feature that will be readily available with additional costs to them in the near future.
