I am sure, that is exactly what I was told as the reason to expedite adding them.
And yes, v4 was missing data for GD-ROM and CD-ROM rips. v5 has correct information on gaps and the v5 support code in MAME supports important things like redbook playback of pregap sectors that didn't exist in the original file. Plus of course it compresses better.
