Unbundling is always better to do in a snippet.  It leads to less
bandwidth usage, and users can more easily inspect the (actual) code.

For other kinds of patching the boundary is less clear.  Generally,
Guix-specific tweaks should be in a phase, but "universal" bug fixes may
well be in a snippet.

I sometimes imagine a downstream distribution that use Guix sources, but
not the build scripts, to draw the line.
