It's not just knowing what the conventions are, but understanding them, i.e. being able to use them well.
OK, I suppose it depends what the purpose of the rating is. If two players both know the BBO advanced stock convention card in details then you could say that they are compatible partners, even if one of them is a good player and gets a bit frustrated if his partner can't count to 13, convention expertise nonwithstanding.
Maybe, when looking for a pick-up partner, I should be looking for someone who knows my system, while when looking for teammates or for opps for a training sesion I should be looking for good players and don't care if they have ever heard about transfers and negative doubles.
But even then, if it is really more about knowledge than about skills, I wouldn't put things like transfers and 2/1 on the list. Yesterday I played a tourney with a self-rated advanced player who had Niemeijer, Ghestem, Muiderberg, Roman carding etc. on his profile. He made some astonishing bids including a double of a 1

If you want to start training for becoming a bridge teacher or TD in the Netherlands you first have to pass a bridge knowledge test. It is about things like hand evaluation and ability to solve problems like the ones Ben posts here - you don't have to know any conventions at all in order to pass it. It still doesn't translate into playing ability - I passed it easily while I know better players than me who failed. But at least it is relevant for some purposes.
