Move https://github.com/matrix-org/glossary into docs?

It might make sense to move https://github.com/matrix-org/glossary (and the repo it mentions) inside the docs matrix.org page instead.
It seems like a logical place people would be looking for something like this outside of spec itself.

(cc @turt2live anything from your or I guess SCT side against doing this?)

Start by reviewing the matrix.org documentation structure and the linked matrix-org/glossary repository to understand how the glossary is currently hosted and referenced. Clarify the intended destination, what content or repository references must move, and whether the existing glossary should remain available; done means the glossary is discoverable from the relevant docs page without breaking its current references.
