I think a few of us are torn on this. If it were accepted upstream, I'd
probably take it. Whilst it is still pending, I'm less sure.

Having "embedded" targeted features in OE-Core is desirable in many
ways. In this case the target usage is probably quite niche.

I'd like to see if anyone else would find this useful? Does AGL want to
use this for example?

If so, I'd probably merge, if not, it is probably something for your
layer. I am happy to see it submitted to upstream though.

Cheers,

Richard
