No, this is not really a fix: I don't want to change the behaviour here from 2.1.2 to 2.1.3.

1)as RFC4862 section 5.5 statement: Creation of global addresses as described in this section SHOULD be locally configurable. However, the processing described below MUST be enabled by default. 2) In other TCP/IP protocol stack, such as Linux and FreeBSD, the IPv6 autoconfig is enabled by default. so I suggest that IPv6 autoconfig should be enabled by default in lwip by setting netif->ip6_autoconfig_enabled to 1 in netif_add, pls refer the attached patch.
