I do not have that plan yet, as product definition for cloud-based and on-premises is very different. To my opinion it is hard to create easy-to-use product for both use cases
Gitlab is a nice product and the open governance is interesting, but I prefer to minimize the time invested in ruby/ror based applications.
Regarding me, it's either Python or Java, because of the support and R&D put into these. Plus it's easier to reuse parts of Java/Python projects in other projects (as they are often written in Java or Python too).
