If I could add my $0.02 (even though I'm not current on all the
discussions and details):
- I believe http://[fe80::%eth0] _used to work_ in Mozilla browsers;
  we're talking maybe early 2000s. The earliest version I can find online
  is c. 2015. Pretty sure I might have old VMs that can demonstrate
  the functionality. (Let's assume there's an existence proof for parsing
  a naked '%' between square brackets.)
- If this has to be approved by the browser community as a condition
  of it becoming widely available, do we know if they will support link
  local addresses in principle? (If not, then the utility of this for e.g.
  consumer router setup is moot.)
- If the browser community can support this in principal, then we can
  discuss EBNF. I strongly favor the syntax above, but any single char
  is better than "%25". Certain OSes (not naming any names) use
  numeric ZoneIDs and I think the cognitive dissonance of "%25<nn>"
  is problematic.
- If the browser community cannot support this, then we could perhaps
  develop a patch for cURL to make it available at least for the engineering
  community (I haven't checked cURL to see if it's already supported).

Cheers, Kerry
