This proposal effectively opens a new side channel for debugging with several
commands ("events", "find", "findclass", ...). This will surely end up in
troubleshooting recipes and other documentation. For now, the commands look
benign but it may be tempting for people to show up with changes that extend
this for other things. So I think this feature needs wider review and a CSR
should be submitted for this.
