>> I’ve never liked this best-tool-for-the-job mental model with software engineering.
I don't either. As photographers say, the best camera is the one you have with you. Same thing, the best tool for the software job is the one you already have and everyone knows how to use. Why anyone would want to introduce these high-end fads to an organization without proper reasoning is beyond me.
That’s definitely part of it. Another part is just the various multipliers you get from having a small number of tools. Team mastery, more mobility of personnel (no/low ramp up times), unexpected opportunities for re-use, high quality onboarding due to narrow scope, etc.
