Yes, we all know Lorenzo's opinion, and the follow-up comments there
give the opposing opinions.

Neither does the IPv4 standard, if we're being pedantic.

It happens to be preferred by a lot of enterprise network operators, so
equipment vendors & o/s really need to support both.

(Also, looking at the history of DHCP and ND/RA, DHCP is not actually
archaic; it's only about 3 years older than IPv6, and was not generally
available until after ND/RA was designed. IPv4 was very annoying to deploy
and prone to fat-finger errors before DHCP was retro-fitted.)

Absolutely correct, which is why I find the Android choice short-sighted.
Having to install this as an add-on seems very unlikely to produce "PROPER"
support. The first user comment for that add-on is "Doesn't work. There is not
enough space in /system...". Duh.
