As a programmer myself, I would prefer to have native IPv6 support so that I can test/debug my programs for IPv6 compatibility more efficiently.

And some researchers said that IPv6 may be faster than IPv4. https://www.theregister.co.uk/2016/07/28..._the_time/

Glad that you say you consider to put it into your "To-Do-List". But it is fine to keep it IPv4-only because I know this VPS 18 should be primarily for running game servers.  

And some game server doesnt support ipv6 and the player most of the time still use isp that doesnt support ipv6 . So it is make sense to still use ipv4
