Using XF1.2 to XF1.3 as a comparison, XF1.3 was
small and lacked much impact due to lacking features, and mostly being quality of life (I think RM1.1 was the main focus at the time). I do not remember if it bled through here much, I remember there being a lot of dissatisfaction and disappointment.
There was only a ~6-8-month period between XF1.2 and XF1.3, which would likely be what incremental updates would look like.

Apple is not the best comparison as their announcements come with a ton of other hardware, and the user base is (stupidly) fanatical.
Incremental updates will just delay the inevitable complaints about big feature updates. Then again, people are never happy and always find a reason to complain about every update regardless of whether it is big or not or delivered faster than current updates.
