I agree. The vast majority of people are just interested in the 2d

Another issue with 3d is how transform-style [1] is treated.
for intstance:
<div id="a">

<div style="transform: rotate3d(...); transform-style: preserve-3d">

<div id="b" style="transform: rotate3d(...); transform-style: flat">

Does it make sense to transform point between a and b?
