Is it possible to unset some of the options when using extends?

Original blueprint:

size:
  default: full-width
  label: Size
  options:
    full-screen: Full screen
    full-width: Full width
    large: Large
    medium: Medium
    small: Small
  required: true
  type: select

This is not working:

background:
  extends: fields/background
  fields:
    size:
      options:
        full-screen: Full screen
        full-width: Full width
        large: Large

This is not working:

background:
  extends: fields/background
  fields:
    size:
      options:
        medium: false
        small: false

I solved this by doing the reverse.

Original:

size:
  default: full-width
  label: Size
  options:
    full-screen: Full screen
    full-width: Full width
    large: Large
  required: true
  type: select

Extended:

background:
  extends: fields/background
  fields:
    size:
      options:
        medium: Medium
        small: Small
