Actually, we are almost there after new indexing for chunked datasets were introduced in 1.10.0.

Current APIs and programming model still require to use H5Pset\_chunk but this call could be omitted if there is only one chunk (i.e, contiguos storage). Then compression can also be used on “contiguous” dataset.

I couldn’t convince Quincey to introduce this change in 1.10.0 and the rest is history.
