Not supported in the sense that no-one tests it before release, so it's not
that surprising if it doesn't work.

I wasn't saying we wouldn't accept it, but maintaining such support is
additional work; it's an extra option to test like Zero or CACAO support. So I
would like some motivation as to why to support it. Is this something you will
continue using and report if it breaks again?

Do you know why they do this?

For 6 & 7, that would be us anyway ;-)

I've made this an enhancement request for 2.7.0.
