There're at 4.0.5 right now, and 4.1 is still very fresh. If I'd have the need for it (actually was already considering it for our project), I'd rather port it to 4.1.

By "vendor BSP", you perhaps mean certain soc or board manufacturer stuff ? Just dont use it, it's usually horrible crap anyways. These usually are fire-and-forget showcases, not suited for production use.
