Generally, I agree with you, except for the argument that developers who play with (or do projects using) less popular languages "are statistically more likely to care about their craft" (do you have any data supporting this claim?). Being curious, while certainly a valuable trait, is not equivalent to "being caring" about some craft - it is a nice addition to the package. However, it is a bit more nuanced than that. For example, success or failure in using this strategy depends on startup's stage, funding, roadmap, team size, engineering culture as well as current or potential use of microservices architecture, which gives us much greater flexibility in a relevant technology stack selection.
