Totally agree with this.  Confidential Computing is a very niche use 
case, and there is no justification for exploding the complexity of the 
standard OVMF build.

If, several years from now, it ever reaches the point that the majority 
of real-world workloads are using TDX, then there would be an argument 
that the complexity cost has to be paid and that the standard OVMF build 
should include TDX features.  But that's several years away and may 
never happen.
