I guess my whole claim is that it's useful/better to declare it
invalid in contexts where you really want text, as opposed to an
arbitrary binary stream. I don't see why it's useful to declare it
valid. I don't see the practical importance of the utf8 spec as the
arbiter of validity here.

I see why it's useful to have some codepaths that handle binary
garbage (an arbitrary stream), I see why it's useful to have a
codepath that handles non-nul utf8, I don't see why it's useful to
handle utf8-including-nul because all the use-cases I can come up with
would equally apply to arbitrary binary data.

What is the example where you want to allow utf8-including-nul that
would not equally argue for handling arbitrary binary data?
