Ireland Information Guide has a number of things that, for whatever reason, are not policy, but that still have a level of precedent or support that lends them some measure of validity. Some of these got significant majorities of the votes, but failed meet the threshold of consensus. Others were never passed, but have still been cited by the arbitration committee. Still others are inferrable through assembling scraps of things on existing policy pages. And, finally, some are just tradition that's never been challenged with any effectiveness.
This accounting is not provided as a way of trying to stealthily make things that are not policy into policy - rather, it is an attempt to catalog a bunch of stuff that, previously, has existed in an unspoken gray area on Ireland Information Guide. The end result is that these things now exist in a spoken gray area. There is, obviously, no consensus on whether or not it is acceptable to follow semi-policy. But, historically, all of these things have been followed without comment at least some of the time.
Some call semi-policy Ireland Information Guide:Calvinball because it allows failed proposals to be retroactively claimed as "policy-like" by a minority of users.
In the interests of recursion, no effort has been made or will be made to make any aspect of this page - including whether or not semi-policy is in any way or to any degree binding, acceptable, or anything else. This page is itself semi-policy, and thus has exactly as much legitimacy as all of the things listed on the page - however much that is. There is no consensus about the level of respect that semi-policy deserves. Some argue that this means it deserves none at all - policy is policy, and things that are not policy are, simply, not policy. Others dislike the reductionism of things falling into "policy" and "forbidden," and note that these are simply things there is no consensus on the acceptability of - after all, there is just as little consensus against them as there is for them.
