The only official train motor in LDraw is from 1991 with fixed wheels?

I am somewhat shocked that the only official train motor in the LDraw library is the old one from 1991 with fixed wheels:

But since 2006 (!!!) a new type of motor with axle holes was introduced:

https://www.bricklink.com/v2/catalog/cat...P=87574c01 (2010 - 2015, "Power Functions" version)
https://www.bricklink.com/v2/catalog/cat...=bb0896c01 (2018 - 2020, "Powered Up" version)

But it seems no official parts for this "new" type of motor. There are some unfinished designs only, like that:
