Interesting overview!

Some of this caveats are kinda surprising for me, coming from a Mercurial background:

* Every time you add a submodule, change its remote’s URL, or change the referenced commit for it, you demand a manual update by every collaborator. Forgetting this explicit update can result in silent regressions of the submodule’s referenced commit. -- This is something handled automatically in Mercurial. Is there any reason why the same behaviour is not used in Git?

* Commands such as status and diff display precious little info about submodules by default. -- This should be possible to implement, no? It's also something that's available in Mercurial (using the --subrepos flag), and it's a huge boost to usability.

Not just them. git archive and git grep for example totally ignore submodules. The whole thing is bolted on, with minimal integration into the core commands. So, usually something to avoid.
