I will speak with my OCaml maitainer's hat, but what I say is not really
specific to OCaml.

For example, each OCaml transition involve rebuilding a lot of packages
(about 139), with 6 levels of dependencies. So if some build takes 2
days or more (for the current transition, on some builds, it was even
more than a week) to be uploaded, it means that transition will last at
least 12 days (for the current transition, all packages were
rebuilt/uploaded/installed after 21 days). But most of the builds are
successful (and fast). If packages were automatically uploaded on
success, a dependency level would be cleared at each dinstall run,
meaning the whole recompilation would take less than 2 days.

Now, imagine that during this transition, another long transition (for
another library) starts... The new transition can be entangled with the
first one, delaying it even further.
