First, we have a concept of a `Full` push. Only `Full` pushes will recompute `PushContext` on change; otherwise this is skipped and the last `PushContext` is re-used. Note: even when `Full`, we try to copy as much from the previous `PushContext` as possible. For example, if only a `WasmPlugin` changed, we would not recompute services indexes.
