 The following config options influence the behavior of the clone bundles
 feature:
 
-ui.clonebundleadvertise
-   Whether the server advertises the existence of the clone bundles feature
-   to compatible clients that aren't using it.
-
-   When this is enabled (the default), a server will send a message to
-   compatible clients performing a traditional clone informing them of the
-   available clone bundles feature. Compatible clients are those that support
-   bundle2 and are advertising support for the clone bundles feature.

 ui.clonebundlefallback
    Whether to automatically fall back to a traditional clone in case of
    clone bundles failure. Defaults to false for reasons described above.
