Adding a comment is an easy task.  Maybe you want to create a ticket:-)

FWIW BIND 9 has the following comment (although it doesn't mention the
suboptimal/optimization issues):

		/*
		 * TCP. Build a response dns_message_t, temporarily storing
		 * the raw, uncompressed owner names and RR data contiguously
		 * in xfr->buf.  We know that if the uncompressed data fits
		 * in xfr->buf, the compressed data will surely fit in a TCP
		 * message.
