asterisk users - Jul 2018 - SRV with pjsip on Asterisk 15.5: yes or no?

I'm trying to configure sip2sip, which says:
http://wiki.sip2sip.info/projects/sip2sip/wiki/SipDevicesAsterisk
"Asterisk, is currently unable to handle more that one result for a
DNS SRV lookup, and the Asterisk configuration needed for getting it
work with the SIP2SIP service is not trivial"

It then gives a complex multi-section workaround in SIP. I remember
reading there'd be the same issue with PJSIP, and then I found this
post in the Asterisk blog from 2016:
https://blogs.asterisk.org/2016/04/20/pjsip-dns-support/ which says:
"chan_pjsip will now look for SRV records based on what transports are
configured on the system".

Does this mean there's now a way of doing it? Because
https://github.com/asterisk/asterisk/blob/master/configs/samples/pjsip_wizard.conf.sample
says:
; Hostnames must resolve to A, AAAA or CNAME records.
; SRV records are not currently supported.

Hmmmm... I'm confused!

SRV support for inbound matching was added after that comment was written.
Identifying by IP address resolve a hostname down to all addresses (including
SRV) - not just a single one.

Outgoing supports A, AAAA, SRV, and NAPTR automatically.

OK, thanks. Shall I file a ticket to get that example file updated?
