Exactly. I think it's rather stupid to have to do a #define DEBUG to
have pr_debug() print in general.

I see no reason to have pr_debug() be anything different than the other
pr_*() functions. Perhaps the pr_debug() should have been called
debug_print(), or dyn_print(), where it can be dynamic printk or
enabled with a DEBUG macro.

The plist code is a perfect scenario where printk(KERN_DEBUG...) is
appropriate, and using pr_debug() with a hard coded #define DEBUG is
just stupid.
