In reply to Aaron Jorbin.

The fact that the majority of users don't care is not an excuse to do something more lazy, where there's a way to please everyone, making the installation easy and fast, but still giving the user the option of activate or not. That's why I think my proposal is a good middle ground.

Auto-activation also implies that developers needs to keep in mind what is happening after installation, and they should change their plugins accordingly (if necessary). Even if there's an opt-out option, devs should still make changes to accommodate to this. Even if a small percentage of plugins require modifications, I think this is unnecessary.

Again, if there's a middle ground that can make everyone happy, there's no reason to not go that way. Especially if a bit more work on the core can avoid a lot of work of hundreds of developers.

I'm also responding here to your last post, that I just read.
