Comment 8 for bug 660358

(about openobject-addons)
then all the branches which are not against trunk-addons are wasting ~130MB of space on launchpad. There are about 1300 branches against addons, let's hope half of them are against trunk addons (blessed addons), instead of uncertified/community extra addons. Which means that rough guestimate 70GB are wasted by openobject-addons.

The worst bit ofcourse is me uploading 130MB for one-liner commits on a dodgy 3G / small-isdn line.

Also any project that has activly developed / heavily diverged series is suffering from this.

For ubuntu project, branches *are* stacked onto series.
For lp projects, they are *not*.

I remember request to allow pushing to: lp:~/project/series/branch-nick to mimic ubuntu projects, not sure where the bug went now.
