Does this library have support for Kailh Low Profile switches?

And support for breakout switches so you can make a frontplate from fiberglass cheap from a pcb fab?

It appears that the holes for mechanical supports are not assigned to cut the mask layers.
This makes the 3D view appear incorrect.

My Cherry MX switches (purchased from Sparkfun) are the reverse of these footprints, with the higher terminal on the left and the lower terminal on the right, when looking at the bottom of the switch. Am I doing something wrong? Can they just be flipped?

These are 3D files for Cherry MX switches with square hole for LED, PCB mount:

Blueprints for Mathias switches:
https://matias.ca/switches/click/blueprints/

Based on the measurements from the Alps and MX datasheets, the size, location, and angle of the hybrid footprint for pin 1 incorrect. The position should be (-3.155, -3.27), the size should be (2.5, 4.4615), and the angle should be 1381 * 0.1 deg.

Having the MX/Alps switches present in the KiCad standard library would make project setup easier and make it so that there is one single source of truth for the footprint across the community. Plain MX switches and Matias switches have already been contributed.

You can open a pull request for the Button_Switch_Keyboard library at the official repository here: https://github.com/KiCad/kicad-footprints.

I would also be happy to do this if necessary.

I've never seen a commercial keyboard PCB with the elongated holes for the switch pins like this library uses, I was wondering if they were necessary for modern Cherry/cherry clones? If not, what function do they serve?

Also, would it be possible to make a version of the footprints with just the plain round holes? If it's possible I'd be willing to create a PR for it.
