Some history here...
the older versions have errors or are broken to some degree or other. They are not suitable for all TC versions and compared to the current version "submitqc" are missing some key features needed to create consistent extensions ready for submission.
Also, in the past we made some errors with the naming of each extension version. As per the original audit instructions
http://forum.tinycorelinux.net/index.php/topic,330.msg1999.html#msg1999 It's advised to submit extensions without the version appended to it's name, that's a rule we broke in the past but was fixed by the current "submitqc" extension maintainer.
While we have attempted to fix many of these errors as they developed along the way, it is dentonlt (the current extension maintainer AFAIK) who reconstructed submitqc into a reliable cross-version audit extension which produces consistent results. For this he deserves all the credit.
Since we were responsible for putting temporary band-aids on some of the older submitqc versions. With the new submitqc version in place I'm quite confident the community will be better served with these older versions removed completely from all repos.
besides, the older versions did not fit the naming convention (except perhaps the original by Jason)
I was not aware "dentonlt" has submitted an updated "submitqc" extension?? If he had I'd be surprised if "submitqc8" would've been used as it's name.
The only currently functioning version which works consistently across TC x86, x86_64 and armv7 versions is "submitqc"
