You mean, instead of using Docker, building the right zsh version on each
job and use Travis cache ? I am not sure that would work as we would have
to "make install" zsh anyway, so we would need sudo...

The Docker setup makes things very simple on zsh-syntax-highlighting side,
it's only one line (https://github.com/zsh-users/
zsh-syntax-highlighting/blob/master/.travis.yml#L30), so it stays clean and
it's easy to use on other projects as well.

All those PRs were submitted before we setup Travis-CI, I'm not sure if we
can trigger builds, maybe if contributors rebase their branches ?

Yeah sure, it was just easier to setup and to get a dashboard with every
version. We want to make it easy for contributors what their pull request
broke. If we start grouping jobs, log files will be harder to analyse.

Currently build time is 5/6 minutes, so I don't see it as a big issue.
