I only have a small amount of Go experience but in my humble opinion I don't think the lack of features is due to lack of time or funding. In fact it would have probably been much easier to say yes to a bunch of features than to continually deflect and reject the demand for those. I'm sure anyone working with different stakeholders recognises this effect.
They have very deliberately tried to minimise the feature set in order to keep the language easy to learn. C++ is probably the canonical example of a language which hasn't kept the feature set tractable but I'd even argue that Python may have fallen into this trap in recent history.
