If ImageAPI does not require PHP GD2 to function, why does it complain about its absence?

The title asks it all, really.

I do not wish to use the PHP GD library on my servers, and instead have chosen for various valid reasons, to use ImageMagick. Since Drupal does not absolutely require GD to function, I'd prefer to not encounter this situation:

What are the steps required to reproduce the bug?

1. I log into any one of my Drupal websites
2. I see a warning message:
   • One or more problems were detected with your Drupal installation. Check the status report for more information.
3. I click the status report link
4. Drupal proceeds to display another warning message:
   • GD library Not installed
     The GD library for PHP is missing or outdated. Please check the PHP image documentation for information on how to correct this.

What behavior were you expecting?

1. I log into any one of my Drupal websites
2. I proceed to enjoy working with said Drupal website
3. If feeling particularly cheerful, I say or think something along the lines of, "I $term_of_endearment you, Drupal."

What happened instead?

1. I log into any one of my Drupal websites
2. Drupal complains incessantly and in a most dramatic manner (see attached screenshot), about said Drupal website's lack of a library that is not even required for it to function.
3. If feeling particularly grumpy, I yell or think something along the lines of, "Drupal, here's a warning for you! How would you like to be $obscene_adverb . $destructive_command?!"

Can we please stop warning about missing non-essential libraries like this?

Thanks!
