True, but the issue isn't removing files, the issue is generalizing a command for mapping output of a command to another command. rm was just a simple example. xargs is far more useful than simply deleting files.
Removing files is a common need coupled with find yet many readers don't know of -delete; I was pointing it out. That doesn't weaken xargs's valid uses. You seem a little defensive? :-)
Too much reddit perhaps. I use the delete switch myself regularly.
