While agreeing with the main point of the Tooling section, doesn't it somehow conceal the fact that QDM/HQMF has established toolling? - this concerns the entire section, but especially the last sentence "Development of a de novo conceptual model would require..." - why would we need to develop somethinng de novo in light of the already available QDM/HQMF and related tooling?

Existing Wording:

Development of a de novo conceptual model would require building these layers of tooling, or at the very least finding a way to leverage existing tooling to support implementation.
