Yeah, that discussion back then prompted the additions that now allow
mounting (with kernel warning) the "suspicious" file systems.
During that discussion, only reasons for a off-by-one CGSIZE() result
were found, so that ended up to be the criteria for warning vs. error.

Now it seems other variants are found in the wild, and we have to
carefully analyze how they could have happened.

Then we can fix any code that needs fixing and downgrade the error to a
warning for the analyzed cases.
