Readonly vs. mutable

🚀 Feature request
Current Behavior
Type 'readonly string[] | undefined' is not assignable to type 'string[] | undefined'.
The type 'readonly string[]' is 'readonly' and cannot be assigned to the mutable type 'string[]'.
Desired Behavior
Better interoperability with libraries that do not have readonly for all type definitions.
Suggested Solution
I'm not sure whether there's an option I like. A way to ignore the distinction at the Typescript level? .asMut?
Who does this impact? Who is this for?
People using schema with typescript libraries that accept mutable data type definitions instead of readonly variants as input.
Describe alternatives you've considered
A recursive type function that casts all readonly types to mutable.
