Then you're needlessly limiting yourself, as you'd very unlikely run into any verbal abuse.

If anything you'd have trouble getting code in because maintainer thinks it would add more complexity than is necessary, or would make his job harder in the future, or after writing and testing the code, you'd find out you should have been doing things differently, etc. These are much more probable ways to get discouraged from contributing kernel code.

There's a high bar to getting code in, and that can be frustrating. But it also keeps the mainline attractive to users and developers, because of ever improving code quality.
