Comment whitelist – should it be released?

Hello world,

I have written a small module for maintaining a whitelist of anonymous users who are allowed to skip comment approval queue based on name/email combination, with possibility of automatic add/delete on admin publishing/deleting comments.

I have some doubts regarding whether this should ever be released. Essentially, they boil down to guessing if:

a) nobody really needs this;

b) on the contrary, it is going to be declared 'duplicate';

c) as this replicates a known Wordpress feature, it is prone to be exploited, and replicating Wordpress is generally non comme il faut.

Any opinions and rotten tomatoes welcome. :)
