 All the above doesn't explain why you use the repackaged version and not
 the official GAP 3 release from [http://www.gap-
 system.org/Gap3/Download3/download.html]

 > So this is the only place where we can find up-to-date versions of the
 GAP3 package *chevie* to work with unitary reflection groups and their
 representation theory.

 No, the official `gap3r4p4` release also contains chevie.

 > I fail to see what might be wrong with adding support for those packages
 using that "random repackaging" since I and several others need them.

 Because the repackaging seems to made in a messy way, see #19164.
