Suppose you want to override FormHelper::error() on a sitewide level.
You don't want to change anything else, just FormHelper::error().
You've already written the views using FormHelper, and you need to
extend it.
Currently you'd have to reference your form helper (call it
'MyFormHelper' for example) in the view as $myForm->blabla(), after
specifying that you need the helper in the controller, which means
replacing every call to $form->xyz() with $myForm->xyz(), in every
view file.
The point isn't to confuse anyone, it's just to make it simpler for
yourself. You're creating a form, you want to call $form->whatever(),
whether you've changed things or not. Of course, if you get override
the methods to do something completely different then it might get
confusing (and provoke hair loss!), but if you keep things consistent,
I don't think it would be a problem.
Of course, the same would apply to other helpers - want to add a
currency format to NumberHelper::currency(), or set the default
format? You're not changing what the NumberHelper really is, you're
just specialising it for your needs.
Still, it's just an idea. Your view does make sense, it could be
confusing if a lot of changes were made...
