I don't think Lars intended for "dogma" to be hard and fast rules.
And many have misinterpreted his intentions I believe. It doesn't even specify using a digital camera, but many think it's a rule.
It's worth bringing up one of my favourite documentaries about filming, the Five Obstructions. If you watch this, then I think you get more insight into why something like Dogme was even created.
It's one of the best examples I can think of illustrating creative process and how our own self imposed non recognised "rules" are what drives us and by acknowledging them we can better understand our own creative process.
By creating an artificial set of rules (aka dogma) then you are forced to throw away your own unacknowledged self imposed rules.

And the original so called rules of dogma 95...
These rules, referred to as the "Vow of Chastity", are as follows:
Shooting must be done on location. Props and sets must not be brought in (if a particular prop is necessary for the story, a location must be chosen where this prop is to be found).
The sound must never be produced apart from the images or vice versa. (Music must not be used unless it occurs where the scene is being shot.)
The camera must be hand-held. Any movement or immobility attainable in the hand is permitted.
The film must be in colour. Special lighting is not acceptable. (If there is too little light for exposure the scene must be cut or a single lamp be attached to the camera.)
Optical work and filters are forbidden.
The film must not contain superficial action. (Murders, weapons, etc. must not occur.)
Temporal and geographical alienation are forbidden. (That is to say that the film takes place here and now.)
Genre movies are not acceptable.
The film format must be Academy 35 mm.
The director must not be credited.
