`someKey` Not Optional in Schema Type if default is provided

Why, if I have the following schema, is

someKey

someKey

someKey

someKey not optional in type

T

T? I would expect this to be true:

Schema.decodeUnknownSync(MySchema)({}) === { someKey: 'some default' } // true

Schema.decodeUnknownSync(MySchema)({}) === { someKey: 'some default' } // true

Schema.decodeUnknownSync(MySchema)({}) === { someKey: 'some default' } // true

Schema.decodeUnknownSync(MySchema)({}) === { someKey: 'some default' } // true

import { Schema } from '@effect/schema';

const MySchema = Schema.Struct({
  someKey: Schema.optional(Schema.String, { default: () => 'some default' }),
});

type T = Schema.Schema.Type<typeof MySchema>;

import { Schema } from '@effect/schema';

const MySchema = Schema.Struct({
  someKey: Schema.optional(Schema.String, { default: () => 'some default' }),
});

type T = Schema.Schema.Type<typeof MySchema>;

import { Schema } from '@effect/schema';

const MySchema = Schema.Struct({
  someKey: Schema.optional(Schema.String, { default: () => 'some default' }),
});

type T = Schema.Schema.Type<typeof MySchema>;

import { Schema } from '@effect/schema';

const MySchema = Schema.Struct({
  someKey: Schema.optional(Schema.String, { default: () => 'some default' }),
});

type T = Schema.Schema.Type<typeof MySchema>;
