Thanks for all these quite detailed explanation.
Just two words on why I tried to install this release:
I was in the process of automating the regular installation of releases ("weeklies"). [Following the idea of John's shared_stack tool].
Of course, while getting the automatic list of tags, I got this one.
I understand now that this release is "bad", and after all it's not required by our users here at CCINP23.
=> It's straighforward for me to "manually" discard one of the detected releases.
But wouldn't be usefull to tag "bad" releases (with a known pattern) so as to discard them during automatic listing?
