How to add a subcommand that does not require a full config

[Threated]

I am really enjoying the crate so far but I am wondering if there is some way to create a subcommand that does not require a config. This seems kind of difficult with RAII when the args::config is only allowed to be declared on the top level args struct but maybe there is already a way?
My motivation for this is that I want some kind of bootstrap command.
Maybe this could be supported by allowing a args::config to be defined in subcommands?

Maybe my best bet is just creating a bare bones dummy args struct which only has the subcommands that don't need a config and if parsing that fails I fallback to the real one for full help + diagnostics.

So one possible option is to have a config at the top level that has... like all fields have a default value?

And then, subcommands that actually do not need the config simply get all the default values. But it's not great. I'm. I'm thinking of options.
