Calling `initialize` multiple times in one application doesn't have defined behavior, and I wouldn't necessarily expect it to succeed without some between-run cleanup (in this case calling `.clear_instance()` on the...

I don't think the double validation is intentional. I though the held validation was meant to be delayed by hold_trait_notifications, but maybe it's not collapsed properly. But validation of a...

Do you have some sample code that reproduces this? What version of traitlets are you using?

The string associated with a subcommand is what shows up in the _parent's_ help output: ``` ipython -h ... Subcommands ----------- Subcommands are launched as `ipython cmd [args]`. For information...

Makes perfect sense

Right now, the logger is shared, so there is only one application-wide log level. I think to do this, each object would have to have its own logger.

Yeah, I think a top-level `traitlets.get_config` would be useful for linting. For now, you can do: ```python c = get_config() # noqa ``` Since the `get_config` name is injected into...

That would be nifty, but I'm not sure how it could work. I don't know how to handle things like import statements, or other variables in the config file that...

I was about to merge this when I realized the argument should probably be a Bunch with access to the trait instance itself like we do with all other hooks,...

Hm, but that makes it not have the same signature as the method. Maybe I should make the signature `(trait, string)` so it's the *same* as the method? I'm not...
