Should "exists" function from STD be used as a last resort?

There was an undo deprecation for "exists" functions but still in the code it says this:

Note: Do not use this function if performing a check before another operation on that file. Doing so creates a race condition. Instead, perform the actual file operation directly.

So basically this message and the description in the PR, would mean use it but as last resort? e.g: third party scenarios?

Thanks.
