Debugger might be a nice interface for prints in kernel. It is also not usable with distributed systems where prints are also not all that useful and you need some kind of central logging. But developing a desktop application without debugger is like writing code with a line editor. It can be done but it is not very productive (I can still remember editing BASIC programs one line at the time).

I meant "prints" as in "logging events into a file".
