Is it? Why? If you know your aircraft well enough that you can look at the MMEL and say authoritatively "this doesn't apply to my aircraft since we have SB xxxx", then creating an MEL is about an hours' work.
The whole point of this is that the majority of crews not only can't do that, but often there is no easy way for them to find out, rendering the MMEL at best useless and sometimes outright dangerous.
