Would it make sense to have 2 rectangle holes in a PCB, with size of 22x12mm?
The holes are for small servos.
Mounting them in the PCB will be very convenient. I am just not sure how easy it is to manufacture it.
Holes like that are not a problem.
You can use the Solid Region tool set to Cutout or you can draw your shape on the Board Outline layer using the Track tool.
You must be aware that the corners will be radiused. The radius depends on the hole dimensions but is small. There are a couple of posts about this and it should be in the JLCPCB capabilities page.
