Maybe a good idea to leave in mainnet and testnets like Morden and Ropsten.

yea - was also thinking about this when doing the change - but where to draw the line?-)

added a commit with a suggestion

I think this was a bad idea 😢

@Arachnid has expressed that maintaining registries separate from the EIP repo might be premature and I agree with that. This change moves towards that.

We can change it back, but as you may have noticed, many networks are already on that list and this is theoretically endless. This is pushing that responsibility off the proposal. We can also update the link to a different or multiple registries if necessary.

Edit: After thinking about it more, I came to the conclusion that you are probably right. I'll put back the list and we can argue (#1828) about creating an Active EIP to maintain the list. The list to the external list can remain of course.
