Oops I might not be clear enough in my response. With the "Fedora legal
requirements" I meant not only the restrictions what can Fedora ship as
allowed by laws of countries where Fedora is shipping but also the basic
restriction that Fedora imposed upon itself within its roots and that is
to provide only fully open source non-proprietary software (let's not
dive into the firmware blobs issues now, please).

And if trusted boot does not break this core requirement I think it
should be allowed within Fedora.
