OK.

Actually our policy is that when a package A can optionally be used by
package B, then package B should have a dependency on package A when
package A is enabled, which is what Joseph was suggesting.

This ensures that package B gets the additional feature
provided/enabled by package A, regardless of the package build order,
and generally makes sure that the features provided by package A
benefits all package that can make use of it.

Best regards,

Thomas
