What difference does it make, for instance in terms of the total size
returned by “guix size tor-client” vs. “guix size tor”?

Are there other considerations, such as a reduced attack surface?

It looks good to me overall!  Some nitpicking:

We’d rather use ‘substitute-keyword-arguments’ to augment
#:configure-flags without touching the other keyword arguments (there
are several examples in the source).

We generally avoid concatenating text like this, for the reasons
explained at:

Regarding the format of patches, you can take a look at this:
