Nope :)

Platform means any module that can be used to build a runtime product (XE, XEM, 
watch, etc). A runtime product doesn't have to use all modules from the 
platform.

Said differently platform contains all the bit and pieces that can be reused to 
build a full-fedged runtime application.

Note that this is the current definition and this proposal keeps that 
definition.

Yes definitely. I was talking about the distribution part (the creation of the 
WAR). I agree that the templates and web resources in general should be under 
platform/modules too.

Well if git is "bad" then we shouldn't used it but I'd hate to choose to make 
our life really hard just because git has a model that is disk-space-hungry. If 
we don't want to waste disk space we shouldn't use git at all! Imagine: we're 
15 committers and we'll have 15 times the whole history. That's disk space 
waste and is the downside of other nice features of git.

Personally I think we're beyond disk space nowadays in 2011 and I don't see it 
as a problem (note that just using XWiki requires 164MB).
