Asked the opposite way - why is this a core API type of a buildkit interface? Having API calls to various LLMs as core functionality of a build system is just straight up weird. Doesn't fit, confuses developers on my team when they try to read/contribute to our shared build libraries, worries me about the direction the project is going.

Seems strange that especially with the push for modules this was integrated as a core type. It has nothing to do with buildkit or builds.
