I'm not resigning either, but I think that it could be useful to have a second 
RTL maintainer in the current situation.

The number of RTL optimizers not covered by a specific maintainership isn't 
very large so I don't think you would have much more work than with DF alone.
And there are the global reviewers.  But, in the end, it's your decision of 
course.
