Using an idle timer, like window: requestIdleCallback [1], is good engineering. If anything passes that's not good engineering, it's laziness.
I'm not even a JS programmer but I know about timers, idle wait in UI programming is a common pattern. It's the attitude of mediocre engineers not bothering to lookup or learn new things.
If every OS/browser/stock market dev did what they want "because it works" we don't have a working system. We'll have systemic lags making the system sluggish and eventually unusable as more engineers follow the same mantra.

Nah, then it doesn't work.
"It works" is The high engineering bar and it's the hard one to hit.
Oftentimes it's replaced these days with imagined complexity, ideological conformity or some arbitrarily defined set of virtues and then you get a really complicated thing that maybe works some of the time and breaks in really hard to understand ways.
Transcompiled frameworks inside of microservices talking to DBMS adapters over virtual networks to do a "select *" from a table and then pipe things in the reverse direction to talk to a variety of services and providers with their own APIs and separate dependencies sitting in different microservices as it just shepherds a JSON string through a dozen wrapper functions on 5 docker containers to just send it back to the browser is The way things are done these days. This is the crap that passes for "proper" engineering. Like the programming version of the pre-revolutionary French Court.
A simple solution, fit for purpose, that works as intended, easy to understand, remove, debug and modify with a no-bus factor, that's the actual high end solution, not the spaghetti stacked as lasagna that is software haute couture these days.
Sometimes, in practice, the dumb solution can also be the smart one. True mastery is in what you choose Not to do.
I agree with the spirit of your comment; I too hate over-engineering. Choose your battles is an important step in mastery, yes, but being lazy can't be chalked up to mastery.
In this particular case I disagree with using `sleep`; using the idle timer it's not as roundabout as you put it: _Transcompiled frameworks inside of microservices talking to DBMS adapters over virtual networks_. It's a straight-forward callback, some lower-level timekeeper signals you and you do your thing: it's nowhere close to the convoluted jumping through hoops you explain.
Mastery comes with balance: putting in the optimal effort, not more, not less either. Of course, depends on what one's trying to master: job or programming. Former means do the minimum and get maximum benefits from your job/boss, latter means enjoy learning/programming and arrive at the most optimal solution (for no reason, just because you're passionate).
