That's all true- sound stage isn't the best (so that means points 1,2 and 4 are identical!)... but as you mentioned as well, it's neat and tidy- and people outside who look in, won't know you've modified your sound system and it's less likely to attract attention from bystanders. That's the biggest reason why I did it that way too.
