The old name is the result of the perhaps somewhat confusingly named abstract operation OrdinaryFunctionCreate(), which creates an "ordinary object" (https://tc39.es/ecma262/#ordinary-object) in contrast to an "exotic object" (https://tc39.es/ecma262/#exotic-object). However, the term "Ordinary Function" is not used anywhere in the spec, instead the created object is referred to as an "ECMAScript Function Object" (https://tc39.es/ecma262/#sec-ecmascript-function-objects), so let's call it that. The "ordinary" vs. "exotic" distinction is important because there are also "Built-in Function Objects", which can be either implemented as ordinary ECMAScript function objects, or as exotic objects (our NativeFunction). More work needs to be done to move a lot of infrastructure to ECMAScriptFunctionObject in order to make FunctionObject nothing more than an interface for objects that implement [[Call]] and optionally [[Construct]].
