Now that redumper does not create skeletons by default, MPF should probably append skeleton to the redumper command. Not creating skeletons by default for blu-ray discs will avoid long dumping times and bad skeletons with UDF. Additionally, DVD-Video is also currently known to create bad skeletons. There may be more system-media combos that we want to avoid skeletons for?

Personally, I don't want to include by default or include a configuration option to include skeletons until I can get confirmation on why they were removed from default dumping to begin with. If I add either of those, I risk using a feature that might get deprecated or removed.

From the horses mouth:

it often errors out and people think dump failed with error
it's so slow for dvd+
it's easy to do that externally with redumper cd skeleton ...

That is to say, its intended use is as I'm suggesting (append the command), and the reasons I suggest not to run skeleton for DVD-Video and all bluray is why it was removed by default.

Things that will likely change in the future is the compression method used for skeleton files (replacing LZMA, or even removing compression altogether). The feature is unlikely to be deprecated or removed.

Given the information above I believe that adding skeleton to CDs only is safe. I feel it is reasonable to stay that way by default until Redumper adds it back.
