Why not SMF 2 Beta?

[Daddy Poi's Oily Gorillas]

So, earlier, I was thinking how leaders cannot manually add their own members, and they have to get an administrator to do it for them.

This got me into thinking of Joinable Groups, a feature I remember ZetaBoards having.

However, when I looked Joinable Groups up for smf, it seemed to require SMF 2 Beta... (Or something like that.)  http://custom.simplemachines.org/mods/index.php?mod=2716‎


So what are the pros and cons to upgrading to smf 2? And should we upgrade? (I am not sure.) (I am not even sure if "upgrading" is possible, or do you only have that option when you first make the forum?)

To start off, here's a list:

Reasons we should upgrade:
Joinable Groups (For clans)

Reasons we shouldn't upgrade:
SMF 2 Beta may contain bugs? (Since Betas usually do before they reach Stable...)
Edit: 23 mods stop working.

Negative:
The 23 modifications installed on the forum will stop working including the downloads section, shop section, badges, the shoutbox, and more.

Okay thanks, I didn't know. But still, is it possible to even manually install the necessary parts of SMF 2? (Not all of it.) Or is SMF 2 done in such a way where it revamps everything?

I have not reviewed the code at all.
