I did.
I could read:
This feature of having a backup artificial horizon based on inferred
orientation from GPS and vario data is useful, and reasonably well
tested, but has the issue of potentially invalidating use of XCSoar in
FAI contests due to rule ref Annex A to Section 3 (2010 Edition) 4.1.2
"No instruments permitting pilots to fly without visual reference to
the ground may be carried on board, even if made unserviceable." The
quality of XCSoar's pseudo-AH is arguably good enough that this
violates the rule. We need to seek clarification as to whether this
is the case or not.

And this feature is included in the 6.2, it does not matter if disabled or
enabled.
The US RC is requesting that such code is not inside the executable.

So the 6.2 version is not compliant to US RC rules.
Instead of trying to help people cheating, I suggest you release a
competition version of xcsoar too.

Thanks for the nice suggestion, but I suggest you actually read and
understand the code before drawing (the wrong) conclusions.
