webserver

I have several dedicated servers and VPS servers, and some of those are at companies that have provided me with native IPv6 blocks (in addition to the IPv4 IP addresses).

Does it currently make sense to point an AAAA record to an IPv6 address on my server, in addition to the A record pointing to the IPv4 address? This would be for (for example) the www subdomain. (the networking and web server software would be set up on the server to respond appropriately).

A while ago I read that a small percentage of users (1 in a thousand?) would have slow or no access if a subdomain had both A and AAAA records because their networking software asked for one and got the other. Is that still the case, will adding an AAAA record inconvenience some users, or is the percentage already smaller and falling?

In other words, is now the time to get around to adding native IPv6 support for a busy website aimed at the general public, or is it still too early?
