Not that I can see. Does this imply that attributes declared at the
class level should be declared with Traitlets? (Sorry, a bit new to
this part of the codebase.)

Since rendering a notebook is a complex process that it might be nice
to have some feedback on throughout, should we maybe inherit from
LoggingConfigurable?
