I don't see how that's an advantage for developing on
branches as compared to developing on the trunk and branching
X near it's release with a later branch for Y.

Depending on the nature of the system, you'll likely eventually
run into a situation where one or more customers can't or
won't upgrade at the same time as the others and then
find a bug you have to fix in their older version. If you
branched for the release, you already have a place to do
this work.

>>>>>>> I think I underand now. Are you talking about software that's going to get shipped out to customers? I'm talking from the point of view of a web-based system, where they all access the same instance of system. My changes are all on a branch too. The change only gets released when its ready, so while it's on the branch I can mess around with it as much as I want. Customers will not refuse to use the system, because the trunk only ever contains code that has been accepted by the customer. Sorry, I should have stated that originally.
