(in favor of using ECDSA instead, if not wanting to use RSA) Cutting it out of the spec would get rid of a fair bit of obsolete text that doesn't need to be there anymore, which would simplify things a bit. Did we ever get to a point where consensus could be called in favor of killing it?

The usage of DSA certificates is so low that I know about 4
certificates that didn't expire yet, but haven't seen any for
more than a year.  Firefox recently (March 31) stopped supporting
DSA certificates and I don't know of any problems with that
change.

So I see no need to support it in TLS 1.3.
