As a data point, the entire diffstat for the update is:

 changelog                                                             |   13 +

where the patch's diffstat is:

+ doc/ChangeLog | 14 ++++++++++++++
+ src/proxy.c       | 12 ++++++++++++

Right now, that diff is available at
https://release.debian.org/proposed-updates/trixie_diffs/exim4_4.98.2-1+deb13u3.debdiff

As you can see, nothing in the update touches functionality outside of
the PROXY module.
