Interesting idea. Almost more of an "armistice", since it would involve the players following T&Cs and getting clarification in advance on gray areas.
Of course, thsoe players that DO scam the system (multiple accounts, etc) probably would not agree.
However, the other part is pretty interesting. Sort of a "minimum acceptable standards" for casinos. A lot of good ideas, many seem targeted towards current failings of many
RTG casinos (which, well, makes sense). The only one that even might produce some trouble on the technical side would be the playthrough-measurer, because
RTG coupons don't have consistent playthrough requirements.
