> [@Karl](#): > > I find it strange -- this proposal is suggesting that we remove a language feature, yet the reason for the feature's existence remains "not clear" and left to speculation. Even though I find given explanation to be perfectly plausible, we really _should_ have this confirmed else there is a danger that we may be overlooking something. Oh, sorry for not addressing this question more specifically early; I hadn't realized it was such an open question. This part of the global actors proposal came from the observation[\*] that the presence of `@ObservedObject`, or other property wrappers that had to be used from the main actor, were a strong indication that the enclosing type itself could only reasonably be used from the main actor, and the general desire to lessen the `@MainActor` annotation burden.
