Even if it is required, that doesn't mean any cards will be retired any time soon. There will still be active projects using Compute Capability 1.x or 2.x.
As long as the client/server is able to identify which capabilities you have, new projects can be restricted to hardware with the new capabilities. Older projects which currently run with lower capabilities will still be in production and the servers will be given the responsibility of limiting assignments to match what your hardware can do. (At the time that Core15 was new, it didn't immediately force the retirement of all older GPUs. There were still projects that could run on Core11 and they were still productive. Similarly, Cores 17/18/21 have been out quite some time before the last Core15 projects were completed.)
Eventually, more the GPUs with more limited capabilities will finish whatever projects they are capable of completing and only then will the older cores be retired.
You'll notice that the V4.4.15 client (and beyond) now reports Compute Capability of your GPUs.
