I have mixed feelings on this. Whilst I can see the attraction, extra
tasks like this do actually have a parsing overhead. We already have a
lot of them and its only a question of time before someone wants
another XXXall task adding.

I'm wondering if we can solve this at the bitbake level instead with a
new parameter instead? That would allow us to delete tasks and speed up
parsing rather than slow things down.

Cheers,
