In reading the Rules of Chess, I noticed something curiously interesting
Article 5: The completion of the game
5.1 |
a. |
The game is won by the player who has checkmated his opponent’s king. This immediately ends the game, provided that the move producing the checkmate position was a legal move. |
b. |
The game is won by the player whose opponent declares he resigns. This immediately ends the game. |
Notice that there is no stipulation given for losing on time in Chess itself.
However, time control does come into play in Competitve Chess
COMPETITION RULES
Article 6: The chess clock
(etc.)
So, I'm not going to draw any conclusions other than to point out that Time Control does not seem to be an integral element of chess, but rather an integral part of official or sanctioned competition. How this relates to the debate at hand is up for grabs.
Well, I agree that measuring rating should be done separately, since rating should be a measure of your strength AT a specific time control.
For the rules of chess, at least how FIDE defines them (so pretty much universally accepted):

EDIT: Articles 1 - 5 are pretty much the rules for are you playing chess? i.e. even in the park without a clock. I would say these are what make bullet chess real chess, and not something else.
After that, FIDE specific competition articles are detailed... note a lot do not even apply online for ANY time control (touch move, pressing clocks, calling flag-falls etc.) since FIDE is almost entirely concerned with OTB competitive play, and has had almost nothing at all to say about online chess.
