Yes I know it's why I will use the reverse proxy : if someone want to access status.vini/something he will see social.vini/something but in the adress bar the URL will be status so it won't break links etc :)
I hope the salmons ostatus etc URLs are like the avatars -> updated so I hope that if I change with the reverse proxy other instances will still be able to contact my instance and maybe the salmons URLs will be updated 2/3
