Distribution Wizard orphaned extensions step is proposing to promote to top level extensions that are dependencies of invalid extensions that will get upgraded in the next step

Consider the following situation:

• extension A that depends on extension B
• extension A is installed at version X on XWiki 12.6.5
  • version X is not compatible with XWiki 12.10.4
  • extension A has another version, Y, that is compatible with XWiki 12.10.4
  • the version of the dependency B doesn't change between version X and Y of extension A

On an XWiki 12.6.5 extension A version X is installed.
Perform the upgrade to XWiki 12.10.4.

After the upgrade, the "oprhaned extensions" step comes before the extensions upgrade step. At this point, Distribution Wizard will identify extension B as orphaned and only give 2 choices it for it:

• promote to toplevel
• uninstall.

Right at the very next step, which is the extensions upgrade step, extension A version X will be found as invalid and will get upgraded to version Y which correctly depends on B, so B is not actually an orphaned extension.

So the actual result we want for extension B is to keep it, as a dependency, of the valid extension A version Y, and there is no way to achieve this during distribution wizard.
