It would be an awful option, think of the diversity of excel users. Millions of them would struggle to understand that here, this time, that does not represent “equal or greater”, and it would be an endless source of confusion.
More importantly, regularity is nice, and Excel already has no syntactic delineation between functions and special forms e.g. IF will only evaluate the expression matching the condition (though AND and OR are somewhat unexpectedly eager).
You're right of course, but I secretly dream they would just change the syntax to straight up s-expressions.
