TortoiseGit hides "gitness" from the user by often executing more
than one git command than is obvious. Hardcore git users get upset by
this, but I personally don't mind except when command line git
doesn't do what I expect because I've become too used to TortoiseGit
(e.g. changing a file while editing a commit message commits the
changes on TortoiseGit, but does not on command line).

That page basically clones and checks out a kitchen sink Boost with
all possible git submodules. That rather makes modularisation

What we really need is for each Boost module to specify its
dependency Boost modules, and that way only the git submodules needed
are cloned. Therefore if I want to use Boost.AFIO in my project, AFIO
will specify it needs Thread and ASIO and those get git submodule
update --init --recursive.

I think the only sane way is to have the master Boost master repo
track which SHA in a submodule's master branch is the sanctified
known true stable incarnation of the library. A library can commit
what they like to whatever branch - and we can't stop them. But we
can gatekeep which SHA in that repo is considered valid by master
Boost master.

We do indeed need a process for automating that, unless you want to
give write access to the master Boost master repo to all Boost
authors (I assume you don't!). I think the hard part there is who
admin's that process.
