Yes, I think we need to go in this direction. The problem is that the container system is yet another tool for researchers to learn. The first step is to get everyone using VCS and nightly testing. Many are still at the point of clumsily written, old Fortran code that gets emailed around and exists in N different variants. (Not that there is anything wrong with Fortran.) Many are at the point where if you email them a link to a git repo to clone, they're clueless about what to do.
