.. or rather, it's probably viable only for distributions that already
have reasons to only care about controlled hardware environments, ie
Chromebooks etc.

But a chome OS install wouldn't care about the whole "secure boot or
not" issue anyway, because they'd also control that side, an they
might as well just enable it unconditionally.

In contrast, the generic distros can't enable it anyway if it breaks
random hardware.  And it wouldn't be about secure boot or not, but
about the random hardware choice.
