What do you mean wrong? Wrong for TDX?

If so, then that can be

Sure, fine by me.

And I don't want a zoo of gazillion small checking functions per
technology. sev_<something>, tdx_<something>, yadda yadda.

So stuff better be unified. Even if you'd have vendor-specific defines
you hand into that function - and you will have such - it is still much
saner than what it turns into with the AMD side of things.
