Check out the sources.list manpage:

And then there's an entire DEB822-STYLE FORMAT section which

Thanks, I see this now. It sounds like sources.list is slowly becoming deprecated - I will consider migrating our repository instructions (and the associated convenience script) to use the deb822 *.sources format instead next time I'm mucking around with our repository.
Ubuntu ships tweaked snapshots of Sid for most stuff, and that dates since well after Stretch froze for release. Of course, try it to be sure, but I just checked an Ubuntu 16.04 LTS machine and the sources.list manpage there indicates support for deb822. As for Signed-By in Release files, Ubuntu 18.04 does seem to have support according to the apt changelog, any version newer than 1.3 ought to include support and it has 1.6 so should be plenty new enough for that.
Thanks for the info. Kyle
