Running MySQL Proxy as a relay between a master and a slave is currently not supported.
It might be added as a feature in a future version, but current versions are not expected to work in this scenario.

Lack of this feature limit usage scenarios available for MySQL Proxy. So I'd like to have it verified as feature request at least.

I agree with making this a feature request, but there are more things to cover than just the issue described here.
For that reason I will create a new bug report to track it and link to that from here.

The feature request is tracked by bug#45328.
