A question about --compression pad

Dear sequoia team,

I see that the default parameter for encryption is pad.

I assume that the pad function adds some random chars to the final message, prior encryption.

I would like to ask, if it makes sense to you, if it would be possible to have an additional integer parameter for pad like --compression pad 1024, or say 2048 etc., which users can use, so that they always can choose an integer value they like, depending on their message size, to always have equal message(s) in size?

A use case for that would be the Usenet group alt.anonymous.messages, were users could then post public key encrypted messages, done with a pub key, without a UID, which then would have always the same size.

Best regards Stefan
