I get it. Yes, stable and productive frameworks would win out in a fair fight, but it isn't a fair fight. The warts in the stable, productive framework are known, and there's already mid-level devs with battle scars that are clamoring for something better than the stable, productive framework.

The alpha-quality software is all new shininess, sometimes with explicit promises of solving the warts of [STABLE FRAMEWORK]. Plus everybody seems to think that new shininess looks better on a resume.
