> If you switch jobs every few years, you'll find half your professional time consisting of busting your ass to build up rapport, only to have to start from zero at the next job.

Not half, all of your time will be busting your ass building up rapport.

Lets look at the alternative: you start a greenfield project with no understanding of what the rest of the company's stack looks like. Engineers know some person was hired to do something, and they may be interested in what you're doing, but they're probably not invested in it (the people who hired you are probably more invested, but they're unlikely to be the ones who have a deep understanding of the tech stack). You're facing an incredibly uphill battle here, as there are certainly going to be things that you will need assistance with (custom libraries, weird deployment frameworks, shitty deployment scripts that only one person somewhere knows how to get working etc.).

You may be a super genius, super hardworking person and be able to pull it off. For the average case, I am convinced this is a backwards way to approach the problem.
