Can I offer a suggestion - focus on non-code developer use-cases. It is still wildly difficult to integrate a VCS system into a document-based application, yet this could improve many, many engineering and science applications that rely on text files (simulation configurations, pre- and post-processing setups, semi-manual entry data-backed "dashboards", etc). This is a problem that really needs solving and I don't see anything out there that makes it approachable.

Having built this myself (hacked on top of git) for an engineering analysis platform in the Energy Space, I'd say a good UI (even simpler than GitKraken) and an "just works" integration would be a massive win.

Just my 2 bits.
