Is using the `derive for remote crate` on `Self` a stable feature ?

[Sh099078]

Hi, I recently stumbled upon a neat way to use default implementations of deserialize/ serialize methods on a struct as a base and then customize its Deserialize / Serialize traits a little further (in order to add some integrity checks for example) using the remote derive mechanics.

It is much more concise than the other ways I know of doing the same thing but I could not find a direct mention of that trick in the crate documentation. Can it be considered as a stable feature ? Is it safe to use it ? Or could future implementation changes break it ?
