If anybody wants to work with \mathcode`< = "8000 then things will
likely take a bad turn.

At any rate, any definitions using < and > will then use the catcode 13
version and when spanish is turned on, all of them will break.

There is a reason turning on the catcodes is delayed until the start of
document.
