So here’s the reason they do this, the code REQUIRES GFCI protection at those locations you mentioned. It is also required outdoors and some other locations. BUT GFCI outlets are more expensive. You can actually feed conventional outlets downstream from a GFCI (come off bottom terminals instead of just a parallel pigtail) which makes the regular outlet GFCI protected. So the builder will install one GFCI outlet and then feed the other outlets required to be GFCI protected from there. Hope that makes sense. I believe the code also states that any outlet protected by a GFCI (breaker or receptacle) should be labeled as such. But that may be a newer requirement. Bottom line is it’s a few bucks cheaper to do it this way. But when you’re building thousands of houses, it adds up.
