I added a bounty for a question in order to find the canonical answer.
@Valorum found a plausible answer, however, as the wiki didn't referenced it, the answer was shared.
The bounty will end in 6 days and, even though there are some comments popping up, it seems like the answer is "We don't know" (from @ian-thompson).
I am aware that "We don't know" can be an approved answer, but in this particular case there is a bonus involved.
How should I proceed in this situation? Should I accept the answer or wait till the end of the bounty period?
