What this doesn't mention is that it also reads DNS servers from Router Advertisements, which the kernel cannot do by itself. dhcpcd does not perform dhcpv6 as far as I know.
I'm not sure; it might do so nowadays. Does dhclient read DNS servers from RAs in IPv4 mode?
I haven't check what dhclient does, but dhcpcd is definitely not a dhcpv6 client.

It says it is
That's interesting, I haven't seen the manpage refer to this at all. It lists the RFCs for everything it supports: DHCP, BOOTP, Router Solicitation - no mentions of dhcpv6.
And then, there's the source code: dhcpcd-5.6.8/ipv6rs.c, line 819ff:
if (rap->flags & (ND_RA_FLAG_MANAGED | ND_RA_FLAG_OTHER)) { if (new_data) syslog(LOG_WARNING, "%s: no support for DHCPv6 management", ifp->name);
So, if your router advertises that dhcpv6 is available ("managed" or "other" flag), dhcpcd simply prints "no support for DHCPv6 management" to your syslog.
Oh, the git version seems to implement dhcpv6.
