Scalable relational storage is relatively new to industry consciousness (outside of Google, where Spanner is used for nearly everything). Spanner and Vitess existed at Google in the early 2010s. It was mid-to-late 2010s before CockroachDB, TiDB, and Vitess were available as open source. Battle hardened database administrators who've been working with traditional unscalable databases for decades often aren't up-to-date with what's possible today unless they frequently talk shop with peers at other companies or go to conferences. Personally I hope old databases like MySQL and PostgreSQL die out within the next decade. They served us well, but they're 25+ years old and the weight of legacy code plus the need for backwards compatibility is a huge drag on their ability to evolve.
