A 2nd, and any subsequent, query on a TCP connection won't incur the cost of a handshake, and if pipelining is handled correctly - using Nagling, or TCP_CORK/TCP_NOPUSH, then responses can co-habit TCP packets. I can tell from real-world metrics that at least some resolvers do support, and actually make, multiple requests over the same TCP connection - though they are rare.

We at the .hu TLD servers see quite a number of long-living TCP connections from Google IP space. They carry typically A queries.

(In principle there should not be, however the IPv6 sockets API is a bit richer so maybe NSD had problems in IPv4 that it did not have in IPv6, for example.)
