Change is annoying, folk don't like having multiple platforms to talk with. A network is only as strong as the number of participants in ot, and discord has won that by a long shot. I'd love to see Matrox grow myself.

Mate there's a million reasons to not use it, you don't need to make shit up.
You don't need to restart per say, like you could migrate everything but it absolutely isn't necessary; and for a system that's productive id even avise you not to until you're more comfortable with docker.
There shouldn't be any issues with on metal services living together with docker, in fact I have some services running that way myself.
