Switching from 0.2.9.9 to 0.3.0.3-alpha now let 1/3 of my outgoing network traffic to exit ports (of my Tor exit relay) being ipv6. OTOH there's more or less no ipv6 traffic from/to other relays.
Is this (another ipv6) bug/issue in Tor or just expected ?

IPv6 is not used for relay-to-relay traffic (not implemented yet).

Yes, this is expected, we fixed a bug in IPv6 exit policies in 0.3.0.2-alpha.
See: https://lists.torproject.org/pipermail/tor-relays/2017-February/date.html

Relays do not use the IPv6 ORPort at all. Clients do not use the IPv6 ORPort unless specifically configured.

Automatic client IPv6 is a feature that has not been implemented yet. But we need relays to have IPv6 ORPorts before it will work.

The first release with the fix for [1] was in 0.3.0.3-alpha [2].
So if you run an IPv6 exit, upgrading to 0.3.0.3-alpha potentially increases the tor network's IPv6 exit capacity.

IPv6 only exits are still not possible with this patch?
tor@afo-tm.org:
IPv6 only exits are still not possible with this patch?
What do you mean exactly with "IPv6 only exits"?
If you want to add a relay to the tor network that has no IPv4 address: This does not work (for a long time I guess).
If you have IPv4 and IPv6 connectivity but you want to allow IPv6 exit traffic exclusively (no IPv4 destinations):
Yes that is possible, just write your ExitPolicy accordingly.

No, and the reason depends what you mean by "IPv6 only exits".
If you mean "relays on IPv6 without an IPv4 listening port", then no, due to the current IPv4 clique requirement for the Tor network (this needs further research, there might be ways to preserve client anonymity without every relay being able to connect to every other relay).
If you mean "relays on IPv4 and IPv6 that only exit to IPv6" these can be configured:
ExitPolicy reject *4:* ExitPolicy accept *6:*
But relays do not get the Exit flag unless they exit to at least one IPv4 /8 on at least two of ports 80, 443, and 6667. An exit without the Exit flag won't be used by (most) clients.
And Exit port summaries in microdescriptors require a relay to Exit to almost all addresses (they can't reject more than an IPv4 /7 or IPv6 /16). An Exit with an empty IPv4 port summary won't be used by (most) clients. (There is a separate summary for IPv6.)
This is inconsistent, I've opened a ticket: https://trac.torproject.org/projects/tor/ticket/21413
