For a custom topic, it would be nice if http headers were passed through the eventgrid. This way extra information (like correlationid, token) could be passed through the eventgrid.

Do we have any progress on add header to the custom topic. While subscribing to subscriber one must be able to add remove custom headers. This would take Event Grid to next level and make more mature in terms of security. Keeping secrets in URL doesn't make any sense. This is security threat Microsoft is keeping open for intruders. Please share updates if we made any progress on the same.
This would also help with traceparent and tracestate headers when working with microservices
