Ask HN: Demand for software modeling bootcamp?

Something I've noticed in a lot of bootcamps is there isn't much training on software modeling. When I say software modeling, I mean is to use UML to express domain diagrams, sequence diagrams, and state diagrams for developers who want to move more into a leadership role.

Would there be demand of starting a bootcamp for software design online? The targets would be developers who want to move into a tech lead role or to become an architect.
