Is it possible to set "default_variants" per platform ?

Basically, I want to set +aqua for platform macosx,
and +x11 for platform puredarwin or platform freebsd.
I tried the most straight-forward approach, wrapping
default_variants in platform, but it didn't work...

For now I made due with "variant aqua requires macosx".

It should be possible. Off the top of my head:

platform macosx {
        default_variants +aqua
}

platform puredarwin {
        default_variants +x11
}


I also seemed to have the misguided notion that the
default variants would somehow go away when actually
providing some variants ? Not so, I had to give an
explicit "+x11 -aqua" to get rid of the defaults...

I noticed that too. See my solution in the e.g. the minivmac portfile:

if { ![variant_isset mac128k] && ![variant_isset mac512k] && ! [variant_isset mac512ke] && ![variant_isset macse] } {
        default_variants +macplus
}

It gives you the default variant only if you have not already selected another variant.
