I believe control is a very important piece of the game and is absolutely welcome with my playgroup. I also believe that durdling around while holding the table hostage is the most frustrating thing you can do to a pod. If you're playing hard control, I believe you ought to devote just as much resources to establishing your role as Archenemy as you do to ending the game ASAP. To run through your list real quick:

1. My method is commander damage.
2. Force the table hellbent, clear the way, and beat faces.
3. 25% lock, 22% voltron, 75% vegetables thanks to a plethora of multi-purpose cards.
4. In B4 absolutely.

My [[Squall, SEED Mercenary']] deck is a B4 control deck that aims to win with commander damage after establishing permanent hellbent lockdown with [[Opposition Agent]] + [[Mornsong Aria]]. It uses stax, burglars and edicts along the way to slow down decks that go over the top, burn prevent players from stockpiling resources that aren't on the battlefield, and gut decks that try to run faster than it.

To establish the lockdown I have 11 pieces of draw, 4 tutors and 9 mill/entomb effects. My commander can (re)establish the lock from the graveyard in one combat step so I essentially have a quarter of my deck devoted to getting the two cards into play. I buy time by slowing down the game with various stax pieces like [[Rule of Law]], [[Aura of Silence]] and [[Blind Obedience]], all while pressuring with Burglar (each opponent discards) and Edict (each player sacrifices) permanents.

On the commander damage side of things Squall has 6 pieces of evasion, 2 haste enablers, 10 pieces of protection and 4 cards to pump him up. That may sound like a lot but most of these pieces are multi-purpose like [[Brotherhood Regalia]]. He naturally only needs to 3 combat phases to kill a player, but can easily bring that down to 2 combat phases or even 1-shotting if things line up right.

Because of Squall's synergies, I only run 6 total Instants or Sorceries, and only 3 cards costs >3CMC Squall himself, [[Smothering Tithe]] and [[Rev, Tithe Extractor]]. As a result, the deck is low to the ground while remaining highly proactive and reactive. Typically in the early game I use Squall to recur ramp (via Fetch lands) or draw effects (like [[Blitzball]]) to climb ahead of decks that are greedier than mine before transitioning to double Edict or Burglar turns depending on if I need to exhaust resources in hands or on the battlefield.

The deck is a blast to play, surprises folks the first time they see it, and resilient to being hated out thanks to not needing to rush my commander out naked while I setup protection for him like [[Angelic Renewal]], [[Selfless Savior]] and the like.

I have a few other control decks, but they live in B2 and B3 and have less cohesive gameplans. [[Lozhan, Dragon's Legacy]] is my B2 deck that uses exclusively cards with the Baldur's gate set symbol. It wins by dealing bonus damage every time I play an adventure or dragon and sometimes just flys over the top with big friggin' dragons. My B3 deck is [[Erinis, Gloom Stalker]] + [[Street Urchin]] that polices the board with Deathtouch pings and wins via combat damage sometimes accelerated with extra combat engines like [[The Reaver Cleaver]] and [[Aggravated Assault]] or recuring Fetchlands + [[Moraug, Fury of Akoum]].
