I haven't looked at the series, but did you take into account that just
grepping for "host-foo" is not sufficient to know if the host-foo
package is used or not?

Indeed, if a package has:

BAR_DEPENDENCIES = foo

then host-bar automatically has a dependency on host-foo, without
host-foo being written anywhere.

Can you confirm this is something you have taken into account?

Thanks,

Thomas
