I don't think I understand the problem: why would you need "not to
include" tree-sitter.el?  We have quite a few *.el files that need
support from built-ins which could not be available at run time, and
yet we don't hesitate to include those *.el files.  How is this case
different?  I guess some details of what bothers you are missing.
