I prefer to think of the term as "sensible default". A "best practice" is usually not the worst default to have, and if you don't have the time or bandwidth to dive into a problem and just want to pick a solution from a hat, you could do a lot worse.

The danger comes in that when you want to supplant the best practice with a new practice, you have to genuinely understand the problem in your context, and be able to articulate a full explanation about why the new practice has an advantage.

But there is definitely cargo culting around best practices - see using Redux. Core features of your app shouldn't be left to just acceptable defaults, but instead you should grapple with those problems and choose the best possible answer you can at the time.
