Here is what needs be known:

The algorithm change is minimal - adding one test - and brings the Alternate Law "autotrim" behavior to be similar to the Normal Law "autotrim" behavior, so it's NOT something completely new.
The additional test in the algorithm requires a version upgrade in a number of internal specifications, that are documenting that algorithm, and in the user documents. The algorithm change is followed by a change of the software implementation, which depending of programming language goes from a line or two - the additional test - in high level language, to perhaps about 6-10 instructions, in machine language.

Is that a lot? That's about as minimal as one would get in terms of a software fix/upgrade.

A software upgrade is the easiest change, a lot easier than changing hardware, mechanical, hydraulic, etc.. components
