On top of that, this would defeat the intent of design change we introduced to make the set/unset logic transactional: https://github.com/apache/camel/blob/main/proposals/mdc.adoc#proposal

For transacted then its not a problem as it will be forced executed on the same thread, and unset is not needed. Its also better to not unset as then the MDC values are still present if 3rd party frameworks does logging.

About custom intercept strategy then its not the goal to have such hard-core feature as something that just snap in. Camel is a old framework and some part have their own pros/cons.
