Yeah, it's the same here but when actually challenged, airlines are hard put to proove that being overweight is a safety issue. Not being able to fit your crew seat is definite and cannot be challenged.
It can also be an issue on some charter airlines where the aisles are narrower (eg 2-4-2 on the 767, or 3-3-3 on the A330) but I have yet to see an 'aisle test'.
