Does typeshed have a clear policy regarding adding @deprecated to "soft" deprecations?
Frankly, I doubt it; it seems to blur the line between soft and hard deprecation.

We don't even have a clear policy regarding "hard" deprecations ...

Edit: But my personal opinion is that we can be more liberal with actionable deprecations in typeshed than with runtime warnings, since the former only affects developers that are using the items in question, while the latter can even affect users who can't do anything about them.
