By not many people caring, do you just mean no one else aside from myself has brought it up or was there actual discussion?
Is there any technical benefit from excluding it? Again I really don't see how much space is actually saved. I mean Inbox capacity was increased by over 100 times. The additional comments thing I think had a limit of what 1000 characters?
You're the only person I can remember bringing it up.
It's not a matter of excluding it, the system we now use doesn't support it by default. (We don't use the same system as before.) It's not a matter of saving space. The question is, is it worth putting the time and effort into adding support for it when so far only one person has mentioned it?
