Trailblazer Wishlist: Contract with dry-v Schema reusage

from.rb

class MyBaseSchema < Dry::Validation::Schema
  configure do
    # my custom predicates, messages_file, etc.
  end
end

TestSchema = Dry::Validation.Form(MyBaseSchema) do
  required(:foo).filled
end

class TestContract < Reform::Form
  include Dry
  property :foo

  # I'd like to do something like this:
  validation :default, schema: TestSchema
  
  # Or this:
  validation :default, base_schema: MyBaseSchema do
    required(:foo).filled
  end
end
