Yes, I know, but as you can see Steemit doesn't use a database, it uses the blockchain. So if they were to implement space for your PMs and all other users PMs in the blockchain that would be much space that people who run nodes won't need.
Therefore sidechains is a good option, but is still a pretty bad option all in all
I mean pm's in the steemit.com site not somewhere else. (if that's what you mean sidechains) .
