All my beers sit 21 days once the krausen forms.
Have some been ready sooner? Yup. Could I speed up the process on certain beers? Yup. Would I do it? Nope. Let's the beer mature a little, gets the yeast out of suspension after they've cleaned up, and usually allows the FG to stabilize fully. I say usually becuase I have found a yeast that if you let it chillax a month or more, it'll continue to chew down the FG a bit more than you expected (S33).
I'm not in a hurry, and if you have a pipeline rolling you'll be surpised at how fast that 21 days comes due.
This shouldn't be confused with allowing high ABV beers (other than hop bombs) to hang out and really meld together. Those need time to mature, sometimes well into months, to make sure they're ready.
