I noticed it on the spec. I haven't tested Webkit.

Ok. Thanks for the clarification.

I think there could be a use case for same-origin+fragment-less URL
which allows for "internal" tracking but not external tracking.

I admit I don't know.
I felt that there were two orthogonal concerns that were addressed and
thought it would be interesting to point it out. If it turns out only a
small number or combinaisons are relevant or have a use case, I have no
problem with just standardizing these. But I think the proposal should
make explicit that 2 concerns ("when" and "what") are addressed and that
the choice is explicitely made to rule out some combinaisons.
