This is an odd statement, as if pushing along an artificially generated negative narrative. It comes across as not using or having never used what one is talking about. Therefore using hearsay and rumor ("last I heard"), which easily can come from competitors and trolls, as the basis of information versus facts.
Constructive feedback would be going to their GitHub and making suggestions, filing useful bug reports, or helping to implement some feature (for those who are really as technically skilled as they claim elsewhere).
> Has vlang managed to get past its controversies and actually deliver on its promises?
The V project is constantly delivering. This can be seen by their near weekly updates, projects on VPM, projects on Awesome V, etc...
The so-called "controversies", have much to do with competitors and trolls, as with anything else.
It might have all been fixed by now, but it is a fact that Vlang has had listed many, many, features on its homepage (without any indication that they were work in progress) that had no implementation and that had no proper prototype.
The defensiveness of Vlang supporters is not a good look.
