I understand your reasoning.
My main concerns are:
- you might end up with lots of versions and no one knows that is actually
used (so it is difficult to clean it). We saw this in oe classic
- generally the reasons why a recipe has DP -1 are unclear. How would Joe
Average know that if he is using webkit-efl he is better off using this new
libsoup recipe?
- and if a recipe is not well enough tested it should probably not end up
in meta-oe anyway (but better e.g. in meta-oe-next or meta-oe-new or
whatever you want to call the super bleeding edge version)

Best regards, Frans.
