Agreed with good points from Markus and Matt here.

For some general tips, please see:

It doesn't really cover refactoring. From memory, the most successful
(larger) refactoring efforts have been tracked as a blueprint. At the
other end of the scale, the little patches you do before a bug fix
patch, so its a cleaner bug fix, often get reasonable amounts of
attention. Discussing your work with folks on IRC often helps raise
awareness of what is happening.

Its worth nothing, a large part of the current priority efforts are
"refactoring" efforts such that we can keep maintaining critical
sections that have become unmaintainable in their current form. Its
worth seeing how your efforts align with what other folks are
currently working on and/or worried about.

The bigger issue here is we don't have enough folks doing great
reviews compared to the amount of patches being proposed. I always
point folks towards this doc that encourages everyone to help with
more code reviews:

I hope that helps,
