I did not propose to make the matching rules more lenitent.
The only thing I suggested was that we check that we have no
conflicting registrations under such potential matching rules.
And I somewhat already regret it.

I don't think it's a good idea to change the matching rules.
We would get more and more on a slippery slope with bugwards
compatibility (Gresham's Law), and I don't see why we need to
go there when things such as e.g. XML go very clearly in the
other direction, based on very bad experience with bugwards
compatibility.
