Proposal: Bevel for subdivision in blender

imgur.com/BDl42au Hello guys,

I am not sure if that's a proposal or a request for bringing back a feature that was awesome. The bevel modifier (and bevel in general) was working amazingly well for subdivision workflow up until blender 2.74b. After that an update happened and the algorithm was changed and the concave edges worked in a different way that made strong artifacts after subdivision.

I assume this new method have some advantages since the old one was leaving an N-gone but I strongly believe that this old method should be brought back as an option.
