Thread Router implementation

[Rainerlan]

Maybe a dumb question:
Would it be possible to support a "thread router" implementation (NOT a boarder router) which would work w/o any connected "CPU" but only power supplied?
I.e. saving the network credentials, ... on an ini-file which would be stored on the stick itself? (Or configured by other means;))
In other ways: I am looking of a thread repeater using the Conbee 2 or 3 - The (required) OTBR is build by HA & another Conbee using the existing OBTR Fw.
