This alias seems to be set by default in many linux distributions these days (and has been that way for many years now).

The problem is that you get used to this crutch and rely on it, until one day you're logged in someplace without the alias and end up deleting something you shouldn't.

I'm not a fan and normally disable it. Instead, I prefer to be very careful and deliberate when using rm, especially with any wildcards, making sure I'm in the right directory and that the pattern matches what I expect it to.
