It's a common practice even outside of x86.  I'd recommend not taking it
personally.  In the end it's all about what produces better code.

And please don't take this the wrong way, but sometimes it takes a bad
patch to inspire a better one.  I mean that with no disrespect, I myself
have sent many bad patches.

And if you don't like my patch, fine, send a v2...
