FreeBSD’s printf is my goto, too! It’s indeed enormously simple to pluck out, instantly gives you full-featured printf, and has added features such as dumping memory as hex.

Funnily enough we're not even referring to the same one, the hexdump thing is in FreeBSD's kernel printf, I was looking at the userspace one :). Haven't looked at the kernel one myself but nice to hear it's also well-engineered.
(The problem with '%D' hexdumps is that it breaks compiler format checking… and also 'D' is a length modifier for _Decimal64 starting in ISO C23… that's why our hexdump is hooked in as '%.*pHX' instead [which still gives a warning because %p is not supposed to have a precision, but at least it's not entirely broken.])
