Hello, I love the new Pythonic configuration - it's really great and addresses a ton of issues all at once. One thing that bugs me slightly is that all fields in a Pythonic

Config

sub-class are marked as

String | {
    /* One of the following: */
    env: String
  }

in the Dagit UI (or similarly for other types). As I do not use the environment variable route to configure anything, the alternate type

{env: String}

is mostly noise when checking schemas or writing configurations in the launchpad. It'd be great to be able to create Pythonic

Config

sub-classes where that default behavior is disabled.
