I am sending v5 now as I'm away from my desk until Sunday.
As I'm unsure whether or not this just needs a V7_0 and the patch
shown as an example isn't a direct correlation : I've left it out for
now.
I will dig into it further Monday March 28th.

Thanks

We can tackle this after the 7.0 release, then basing it on the new
compat machines and most probably on [1].

Should be easy to adjust.
