It already writes the source IP in the X-Forwarded-For header.

Only if you modify the code. The reasons why Squid does this is twofold:

a) Recommended by the RFC

b) Cuts down on the resource usage on the server as there is
significantly less number of connections open, often several orders of
magnitude difference.

Assuming the connectivity is good Squid -> your_proxy -> origin you
could just as well disable server side persistent connections I think.
