It’s simple cost/benefit.
Cost: More parts, more $, less durability, less parts interchangeability between models with different engines
Benefit: Prevent inconvenience for the extremely small percentage of people that have an issue with the skids as designed.
Get a 3/8" cordless impact gun. I can get the driver side and under-engine skids off in about 30 seconds using mine, no exaggeration. Reinstall is a couple minutes, just have to be careful with the trigger then go back to snug things up with a ratchet.
