I tried 'relativenumber' for a few days. I threw it away as too annoying. Considering the topic here I find it especially amusing that 'rnu' should come up—this is all about focus, and it was the distraction that it was that I hated about 'rnu'.
If you were looking at relative line numbers and typing 8j, you can just as well look at line numbers and type 372gg when you have 'nu' set.
The key to rnu is having a toggle bound. Once I had that it never annoyed because 90% of the time I want an absolute number I just jump to it. For the rest of the times I just toggle.
