Currently manual sync is significantly faster than object sync and RPCs. This is fine... until you are using manual sync to replicate e.g. a control for a particle effect bound to a held object. We need a way to get these back into sync.
Some potential options include:
  1. If the object sync latency is fixed, provide a way to obtain this delay so we can apply it to manually synced values.
  2. Provide a way to attach synced variables that are transmitted on object synced updates, but do not prevent the object from sleeping when it's not being moved (see https://feedback.vrchat.com/udon-graph-upgrade-closed-testing/p/reliable-sync-feedback-please-add-a-way-to-sleep-a-continuously-synced-object)
