Ahh! I did not know that

It's a similar situation with "Arca-Swiss compatible" tripod plates in photography. There is really no such thing — Arca-Swiss didn't make a standard, so they didn't have to stick to it themselves, and while most things using this "standard" fix to most things, some things just won't fit, or won't stay put. Everyone implements it, and if they don't, people complain "why didn't you just put an Arca standard foot on it?" and then you have to sit them down and tell them.
