I think it have to be treated with carefulness.
If the player is begginer or midle level player, should avoid it, Becouse when win the game maybe think he is playing good, and in that kind of chess it is very often to find no so brigth ideas and games, so when try to play the same ideas against someone who is thinking the moves, things can be very different.
In the other end, if a player want to become profecional this is a must skill to be able to play in this way. becouse in tournaments maybe is runing out of time and needs to be able to play fast and good enougth.
So in my opinion a player should avoid this if want to enjoy the thinking of the game, if want to be profecional then should first become a strong and solid player and only then practice the fast games in controled shortining of time, like first games with time control 15 minutes each, then 10 then 5 then 3 and finaly 1.
This game seccions should become with the company of other more proper chess to compensate. Like tactics, openings, or 1 hour games. Also after the game the player should try to play it back by memory, on the board, be able to recreate the moves of the whole game, if is not able then shorter moves, like the game ends on the move 30 at 5 minutes control time, kinda rule. Do not Study this bullet games, do not use them for study, analisys nor make any display of them as example of your game. Asume they are so full of mistakes it is no wortly the time to spend analicing them.
If the player gets a rush for fast moving, then play some ping-pong instead of chess.
That is my opinion.
The big question that always has controversial opinions.. Does playing blitz, lightning, etc ruin or help your standard chess games? Personally I think 1 0 lightning has to be one of the most ridiculous chess variants ever invented
