As the other commenters stated, it is not clear what is the point. Writing good code and being a tech leader are very different positions with very different technical skills. I was a tech lead in a few cases (different companies or different departments of a very large company) and I was not the top developer there, my job was not to be one. I worked with developers that were much better than me that were not a good fit for a tech leader.

I took it as good, central contributions are one path to respect and trust.
