-1 till we solve the question above. I'd rather keep legacy modules than have dissatisfied users.

-1 too, not bundling at least core extensions legacy modules will make EM more or less unusable for many extension older than the current version right now.

3 -1's so there is definitely plenty of agreement in this case. My understanding is that in "Distribute without legacy modules by default" "distribute" means "distribute [enterprise and manager]", which would make this a reversal of the agreement voted upon here: http://lists.xwiki.org/pipermail/devs/2012-April/050386.html At any rate I am curious as to whether the community wants to ever remove anything. If we want to get to the point of removing things then I want to help, if we don't want to then I will accept it.

The way I see it, breaking API and removing code is like taking out the garbage. When you do it, you stink and nobody is your friend. If you don't do it, everything stinks but it does so a little at a time. It seems to work reasonably well.. Oracle, Sun and Microsoft have been doing it for years.

All I care about is that we have a plan, if we want to remove stuff then lets make it happen, if we want to never remove anything then lets make it a conscious decision. I don't like the idea of having the decision make itself while we put it off.

Some design where old extensions quietly pulled in the legacy modules doesn't seem any better than shipping them by default as they will end up installed everywhere anyway. That's what I mean, Sun's policy with Java has been to "never take out the garbage" and the latest version is 150MB after unpacking. I've heard from the grapevine that Oracle has (database) code which nobody at the firm knows what it does and nobody dares to touch or remove it. Microsoft has done 3 major rewrites of Windows (95, 2000/NT, Vista) and done an incredible job of maintaining backward compatibility, at a very high expense no doubt. My point is that not taking out the garbage is an option. It's probably not the best but we wouldn't be alone in choosing it. This sounds unfortunately like "we like to think about it but nobody wants to get smelly". If we want to *not* remove anything then we may have opportunities to improve existing code rather than rewriting it. If we want to actively remove code then we have opportunities to improve the stability and performance by changing execution paths. If we want to talk about removing code but not do it then we don't have any of these opportunities.
