We know we can remove the checks altogether but think there is a more elegant solution that would perhaps allow us to not care about the 1GB changes (as big logs sometimes churn on our IOS-XE devices).

you can create your own device type that does not include the dir commands
or one with your own filter function for the dir commands that removes the
usage line.

otherwise, i havent currently an easier way to filter. I am thinking that
a user-specified post-filter might be useful for such things. I think that
ought to be per-device type. Should there also be a pre-filter? Sexier
would be a context aware filter that retained the changes but filtered the
diffs.

Indeed - We added a couple of device types to cover the nuisance diffs for situations such as this, as it was the easiest way to control when and when not to do things.
A post-filter would simplify a lot of that, though - as I currently maintain close to a dozen diffs between updates for our niche cases.

Not sure about a pre-filter... I could see that having unanticipated results with output from stock rancid functions and cases.
Unless pre-filtered lines include an identifier "this was pre-filtered. Don't touch it" check to avoid such calamities and or confusion.
