Forms mandatory requirements

If you have access to the standard, a quick read will tell you that it's NOT in there. None of those things are "mandatory". The problem with having people tell you that this or that is "required" is that they hope you don't know any different. Check what your local document control procedure(s) say. Your organization may have elected to do those things, because someone thinks that's good practice (it isn't) and unless you can get that changed, you may be stuck with that practice. But it's not mandated in ISO 9001.

 

It's common practice. It's not (now) good practice. Forms don't need numbering. A form can be filed by name. "Effective date" doesn't need to be on the form, the same communication can be made through the use of a Document Change Note which conveys much more additional useful information, like WHY something changed. A revision MIGHT be useful, but there are (electronic) means of achieving the same result that don't resort to "revision" details.
