What I mean:
return App::config([
'monolog' => [
'custom_channels' => [ // <= new name
// ...
Why?
It took me forever to finally understand that whatever you pass there, will never be a full list of all channels (because of Symfony's built-in channels like router or security).
Renaming this to custom_channels would nicely convey the message that more channels exist.
But it would be a BC break.
