Hi guys!

I know we just started adding them, but I wanted to have a conversation about the deprecated warnings being added to 2.7. There have been several issues where the warnings are causing bad behavior (e.g. many systems map all errors to exceptions).

@dbu just talked about this at #12945 (comment), and I agree that it's a BC-ish break. I'm also worried about people getting their error logs filled up with warnings (we can't control what level their logging on production) - e.g. 10 GB log file that fills up the disk space and ends up being Symfony's fault :).

The downside is that we lose this cool way of auto-detecting that you're using deprecated stuff, and I'm not sure if there's a way to keep that.

Ref #12945, #12868, phpspec/phpspec#580, https://twitter.com/lsmith/status/543755471853993986

Thanks!
