Have you thought about the trailing dot? If so, do you have a clear idea (or even strong feelings) about whether it should be either tolerated or forbidden?

It can’t be required, as doing so would introduce pervasive conflict with how libcurl already handles a hostname parsed from a URL.

Is there a reason the DoH code can't just use with exactly the host name it gets passed, using a trailing dot or not?

I forget the exact state of how to deal with the trailing dot in all the different areas right now, but surely that decision could or even should be taken outside of the lower level DoH functions anyway?
