CRLF is obsolete and should be abolished

What would be the benefit to updating legacy protocols to just use NL? You save a handful of bits at the expense of a lot of potential bugs. HTTP/1(.1) is mostly replaced by HTTP/2 and later by now anyway.

Sure, it makes sense not to require CRLF with any new protocols, but it doesn't seem worth updating legacy things.

I'm hoping this is satire. Why intentionally introduce potential bugs for the sake of making a point?

Exactly. Please DO NOT mess with protocols, especially legacy critical protocols based on in-band signaling.

HTTP/1.1 was regrettably but irreversibly designed with security-critical parser alignment requirements. If two implementations disagree on whether `A:B\nC:D` contains a value for C, you can build a request smuggling gadget, leading to significant attacks. We live in a post-Postel world, only ever generate and accept CRLF in protocols that specify it, however legacy and nonsensical it might be.

(I am a massive, massive SQLite fan, but this is giving me pause about using other software by the same author, at least when networks are involved.)

What a weird reaction. Microsoft’s use of CRLF is an archaic pain in the ass. Taking a position that it should be deprecated isn’t radical or irresponsible — Microsoft makes gratuitous changes to things all of the time, why not this one?

Hipp is probably one of the better engineering leaders out there. His point of view carries weight because of who he is, but should be evaluated on its merits. If Microsoft got rid of this crap 30 years ago, when it was equally obsolete, we wouldn’t be having this conversation; if nobody does, our grandchildren will.
