The way I'd describe what I see from V's author from his two projects (V and Volt/eul) is a continual over-promising and underdelivering - as well as misleading statements (for example, a claim that V is the "fastest on Tech Empower's web framework", which is actually fastest in only plain text (it does not do enough to be qualified on the full leaderboards) on an unofficial run (it is currently 2nd I believe), where it is simply a wrapper around a C server [1][2][3] - which I believe is misleading, even if the C interop is neat). That is not to say he cannot eventually deliver on his promises, but they frequently take years beyond his initial predictions, and sometimes come watered down.
My personal conclusion from my reading was - if you wish to go use V, go ahead, but I'd exercise caution when relying on anything about it.
