If we can offer an API compatible solution in 1.11, that would permit drivers to be back-ported to 1.11, which would be nice. Not critical, of course, just means that drivers would have to support both the 1.12 and 1.11 interfaces for a bit longer. However, it sounds like these are two slightly different solutions to the same problem, right? -- [email protected]
