That's a good option. Also emil, I don't think you need to be too stringent with the data sharing. The author can also publish the covariance matrix (+ variance, Mean, SD). With that, the reviewers can use them and replicate the results. Even this is really an improvement. If you look at most studies in other journals, you don't see the covariance matrix reported. Apparently it's not obligatory. But it's a defect. Several times, in meta-analyses, the author(s) mention in their inclusion criteria that they select data for which they have the variance/covariance matrix.

By the way, I remember 2 times when I asked data (by mail) to some authors. I knew they wouldn't give me the raw data, so I asked only for the correlation (or covariance, or both) matrix. I have been told by them that the data do not belong to them and that even this is not possible. Once, I have been told that they don't have the data.
