With the documented postfix third-party interfaces -- policy
service, milter, smtp proxy, content filter, TCP tables, other stuff
-- care is taken to maintain compatibility between versions even as
features are added.

Care is also taken to document the expected data exchange format,
and to document any changes introduced by software evolution.

As a result of this time consuming design and testing process, the
vast majority of third party plugins will work with their designed
version of postfix and later.

The original poster is apparently referring to a very old third
party postfix source code patch attempting to implement libsrs.
IIRC the patch was never stable nor functional at a production
level, and never widely used.  In general, source patches become
less usable as the base software evolves.  I don't know the status
of this particular patch, but I would be surprised if it can be used
with current postfix without major surgery.
Calling it a hack seems appropriate.
