Not really....type of brewing methodology really has little to do with how long a yeast needs to do it's job, or how long you decide that yeast should stay in contact with the wort.
Wort is wort regardless of whether you made it or dilluted it with water. It still has a starting gravity, and srm, an IBU....if you make the same recipe as allgrain or recaluculate it to be extract with grain, it should be EXACTLY the same if you've done it right...same color, bitternesss, and gravity, all the same numbers at the end of the boil....
It's just going to be a bunch of "sugar water" waiting for the yeast to eat it..THEY don't know from AG or Extract, they just know that they have a bunch of fermentables to chew through.....AND it takes them EXACTLY the time it needs to....Timneframes on them are OUR deal not there's, all they know is eat sugar pee alcohol and fart co2.....it really doesn't matter for the source of it.
I leave all my beers in primary for a month regardless of whether they are ag or extract.
