I was wondering how the lossless compression is inferior to uncompressed? Have you found data not reconstituted accurately? Modern algorithms are very very good with constrained data sets like sensor data. A lot of mathematicians would certainly like to see your data that breaks the lossless compression retrieval, in such a closed system.

Personally I think the notion by photographers that raw numeric data is sacred and faithful to sensor excitement, but lossless compression is not, is an old wives tale. Sure, with random data sets it can be broken but even in that case normal lossless algorithms have escape functions if the data is not compressible. But with constrained data sets like RAW sensor/ADC output, it just does not happen, hasn't anyway. Not using it is more of a liability than using it.
That point in your list is really a wash also.
