Hey @DaanDeMeyer. 

I initially thought this was an editorial problem so created #2710 as an attempt to clarify things.

However, I think the question is more philosophical. To analyse it a bit, what you're asking is how to handle an error after the occurrence of a critical connection error. First, a SETTINGS frame on a wrong stream type, then another SETTINGS frame on a wrong stream.

After the first critical error, all bets are off. I'd expect a lot implementations to just give up at that stage as the peer is likely to be misbehaving.
