Given how long this has gone on now, it’d probably be best to inform your community that you’ll be removing BLOBs from the source and for them to be produced during build otherwise this shadow is going to remain.
Many of the BLOBs are essential to allow Ventoy to work with Secure Boot. They are compiled and signed by Fedora and OpenSUSE. They definitely need to be better documented, but they aren’t reproduceable for good reason.
There was a few months where Wikipedia was reverted to a very old version as newer versions didn’t meet their build standards. That has since been fixed.
