We probably should have a stated policy, yes. AFAIK the current perhaps 
unstated policy is to keep the inc file if it existed in OE-Classic.

If you carry over the whole recipe rather than "require recipes-
xyz/foo/foo.inc", then you won't get any improvements to the non-version-
specific parts of the recipe when the base layer updates in the future.

Alternatively if you "require recipes-xyz/foo/foo_6.5.bb" because there is no 
.inc, then your recipe will definitely break the next time the recipe in the 
base layer is upgraded, plus you may have to override more parts of the recipe 
that are specific to a different version than the one you are building.

Cheers,
Paul
