I’m strongly opposed to the

syntax, because there seems to be no natural arrow expression analog of it.
A notation that starts with \ (like “\case”) can be carried over to arrow expressions by replacing the \ with proc (like in “proc case”).
Remember that there is a \ in arrow notation in addition to proc. So one might expect any abbreviation for \x -> case x of {...} to mean the same \ thing in arrow notation too. If the abbreviation contained no \, there would be no way to replace it with a proc.
