Not sure, lxc has always been a little clunkier but if you look at the 80% case of "docker pull X; docker build .; docker run ..." I don't see how that problem couldn't have been solved. (No, this is not supposed to be a "how hard can it be to build your own dropbox in a weekend", but I did use LXC extensively in the past and with a few aliases it was honestly fine most of the time, for the developer side.)
