I am not sure fe80::1 as a default route is standardized in an RFC, so 
to say?

I can agree though it is often used in practice.

Yes, I agree.

Just that some times one can get on-link because one legitimately has 
the credentials, yet one does not know the default route, because it 
does not come from an RA but from a link-layer message exchange which 
might be difficult (impossible some times) to capture.

I am not saying it is good or bad, just I detail the perspective, for 
the sake of discussion.
