I don't see this happening in oe-core or meta-oe, your grep proves it.

Reading it about DP setting or in commit where I've added it?

How will Joe Average know that because of webkit-efl he should enable
meta-efl-next (or
oe-core-next-libsoup-development-version-alpha-centauri-edition layer) 
 if he doesn't even know what's happening in layers he is
using already (meta-efl for webkit-efl)?
