- I think there should still be a form of authorship, specially given that both are copyleft and MPL-2.0 makes it likely to be vendored/reused elsewhere, people typically fail at adding authorship when doing so (and you'd end up with different author lines in third-party software).
   For example:

     Copyright 2019 Hare Authors <https://harelang.org>

- Any reason to not use SPDX-License-Identifier? Which would also mean explicit disambiguity between GPL-3.0-only and GPL-3.0-or-later

(Those two would mean REUSE compatibility btw)

dislike having the year here, could do something like

iirc Drew doesn't like SPDX-License-Identifier? i don't really care
though, and switching to GPL-3.0-only sounds reasonable

To me, this seems useless.   “This file was authored by its 
authors.”   What difference is there between vendored copies 
having no such legally useless “copyright line” at all and having 
one that doesn’t even provide the perceived benefit of some kind 
of credit, like the explicit ones would?

I wish it would be a bit shorter / easier to remember, but sadly REUSE only supports this one.
Not a bit deal but maybe see if it can be changed in the spec?
