Thanks Clement, that’s what I read online as well. But I feel like having multiple builders make it not quite flexible, and may confuse our users. 
Is it easy to enable parallel steps? If I want to do a pull request for it, do you have any suggestions?

However, if you're OK to have multiple builders; you could move each parallelizable step to another builder and trigger <http://docs.buildbot.net/latest/manual/configuration/buildsteps.html#triggering-schedulers> all these spinoff builders from the main builder.
