rtl-sdr sources

Hi, I had a problem with rtlsdr_cancel_async. I find this fork on github that solve my problem https://github.com/pabigot/rtl-sdr nice .. And then realize that there are 46 forks of the rtl-sdr on github.... I know that's how github works , but is there somewhere an effort to merge the best of these mods ? It doesn't seems to be the case on github, but perhaps elsewhere ?
