To be honest, I'm surprised too I did not think about it. ;-]
In fact, as an after-thought, I do know why. That's because I was thinking
the other way-around: a package that depends on a sub-option of another
package, sub-option which in turn depends on a third package. *That* one
would require an _AVAILABLE for sub-options.
For example, libuuid which is a sub-option of util-linux (although that one
sub-option has no dpendency; but you get the idea) is select by a few other
packages (eg. parted, ntfs-3g...).
And going *that* route is IMHO not what we want.
And first, we need to know if the case really exists (I was not able to
find a good heuristic to find such a case with a simple grep, so I gave
up the search).
Regards,
Yann E. MORIN.
