Apparently, folks are working on software driven interpolation algorithms to remove diffraction blur.

Sharpening does a lot of that, but it takes some effort  to get it right, and it's easy to over-do.

A purely automatic deconvolution algorithm for removing defraction is something that works better in theory than in practice. First of all, you need a lot of pixels, but also very low noise; also, the actual pattern of diffraction will vary by lens model, and there is variation between lenses of the same model.
