Hi there! I hear what you are saying especially if you are considering recommending the full single application. As our maturity model shares, we are better at some stages than others. So I would share parts of the product that really work for you all the time and let people experience for themselves.
If I could have GitLab Mature Edition that was restricted to the high quality more complete parts, it would go a long way. Otherwise shipping a product where I have to sell the good parts and hand-wave the rest as incomplete -- it makes the product much less appealing.
