[squid-dev] RFC submodule repositories

[Stuart Henderson]

As a package maintainer: the workflow for package builds on many OS uses
tar downloads and if these are produced by git-archive (e.g. as done on
github's "download source" links) they don't include submodules.

So, if used for some helper which is normally included in OS packages,
submodules can make it harder to test changes from git commits (for
example, to see if a recently committed change fixes a problem).

Of course a tar can be built locally if needed, just adds some extra
steps, and perhaps there are benefits from submodules to outweigh this.
