I think it is more "tact" than "luck".  But we have had some success
in making such requests in the past, generally quiet requests directly
to the developer.  Most open source developers write code because they
want it to be used and for people to benefit from it.  So if you give
them an opportunity for their code to be even more widely used, this
aligns with their goals as well.  But such requests must be made
quietly, via private email, since there is a lot of peer pressure to
be uncooperative with Apache.
