Does @override will be mandatory in the future?

Hi,
I understood in a previous discussion that the @OverRide decorator is not mandatory for now.
Will this be always be the case? Or is there plan to make this @OverRide required in the future?
I have to provide a few recommendation to the team, so I would like to clarify whether or not it is a good practice to put it.

required in the future

Will likely depend on ES decorators spec status/implementation.

it is a good practice to put it

It is:

1. It makes sure the field in super is decorated, which provides similar benefits to TS's override keyword:
   https://www.typescriptlang.org/docs/handbook/release-notes/typescript-4-3.html#override-and-the---noimplicitoverride-flag
2. It's easier to eventually remove it than add it where necessary.
3. It's possible you will have to replace it with different decorator (again depens on ES spec) - besides being easier to locate, we can change the override implementation to provide a friendly warning/instruction (or perhaps even a migration tool).

Ok, super, thanks!
