@jelmer Pyflakes (or frosted really these days) unfortunately doesn't cover even a tiny fraction of the things pylint does. In general in the project's I've been involved keeping the code pylint clean helps more when adding/modifying code, so it's clean from the get go. 

@garyvdm  sure, if you'll do a writeup on the current situation I'll just keep my paws off the code until then.

Even though pylint is noisy, and fairly frequently exhibiting serious bugs, I find it a fairly large net win anyhow for keeping code quality up. But anyway, the dropping of a PR is not the end of the world.
