Yes. And I believe it did because that becomes the only viable reason to exclude the teaching of one widely accepted theory over another. But over the millennia, scientists have debated countless theories that weren't supported by specific, tangible "scientific" evidence. Such debate resolves more than it obscures. And because "intelligent design" is an alternative theory to "evolution" it makes sense to present it concurrently with evolution.
Note that 1) you called it a viable reason, 2) that you’re still not using the term “scientific” theory regarding what should be in a science class and 3) that AFAIK high school science class has never been the medium for teaching alternatives inconsistent with science.
