I think this is just another cultural difference. Git comes from the
kernel environment (although it is currently used in far more
environments than just the kernel and kernel-related stuff) and the
_kernel_'s development style is that you want to get as much stuff as
possible inside the kernel, and on the other hand don't care at all
about breaking in-kernel APIs and such.
The Git "plumbing" is very much the "kernel". We aren't as much
interested in having support for external bits of code poking in the Git
innards, we would much rather have them integrated into Git as soon as
possible rather than live around externally. OTOH, the "kernel" gives a
very flexible ("UNIXy") API to the writhing mass of porcelain scripts you
may call the "userland".
I'm not saying it must be always sharply better approach than the
plugin-encouraging approach. It's just as it is. (Also, another reason
is probably a purely technical one, it is much easier to have pluggable
functions in scripting languages that support "monkey-patching", than
have them in C, since you actually need to explicitly add all the hooks
etc. So in Python, from a large part you get the plugin support for
free.)
