 Outgoing edge transitions can be 1:1 or 1:2+.
 
 ### Transitions on native options
-WARNING: This feature will be deprecated soon. Use at your own risk.
+WARNING: Long term, we plan to reimplement all native options as build settings.
+When that happens, this syntax will be deprecated. Currently other issues are
+blocking that migration but be aware you may have to migrate your transitions
+at some point in the future.
 
 Starlark transitions can also declare reads and writes on native options via
 a special prefix to the option name.
