It's interesting to hear that this was intentional on your part. You're not
alone on this, 3/5 servers that I tested didn't care about the CR at all. My
own server does require the CR, but I didn't like writing it that way and felt
like I had to jump through unnecessary hoops to conform to the specification:

    data = await self.reader.readuntil(b"\r\n")

instead of the more straightforward:

    data = await self.reader.readline()

I would prefer it if CR was optional. Similar to how <whitespace> is already
defined as "any non-zero number of consecutive spaces or tabs". The same
argument applies here. Content authors can't visually distinguish newline
characters in text/gemini files, and I can't tell the difference in my terminal
when I'm inspecting a gemini request.

   <newline> = [<CR>]<LF>
