On the other hand, the memory functions and the conversion functions do have possible platform differences, so tracking them could be helpful. I think the biggest problem is that all of these functions already have versions for all of our supported platforms, so no matter how we slice it the table will just say "Done" everywhere, except for the functions that we haven't started.
Perhaps a more useful way to present this is to just say whether an implementation is available or not. So, just one column `Available` under which you say `YES` if available, nothing if not. You can potentially add a `Notes` column in future to add additional notes if required. For a reader not involved in the development, that something has been designed or not does not help much. A person interested in contributing can engage on discourse et al to gather more information.
