Comment:
I did some experimentation with this and it looks like it's not possible
to distinguish between a truly unknown template tag and a template tag
that isn't registered as a starting tag but might be an ending tag (like
`elif`, `endif`, etc). That's why the error message lists some "expected"
tags.
However I do have personal experience with Django users who have been very
confused by this message and didn't even think to check if they had loaded
the tag. I think your "Did you forgot to register or load this tag?"
message is a good solution. I've created a patch and PR to add that to the
error message: https://github.com/django/django/pull/5392
