There's a known performance issue with hide & friends that jQuery would like to fix.

I've seen browsers leverage console warning used to create positive change.
For example Firefox warns of __proto__ use and this got Zepto to drop it.

I think this same technique could be used to deliver a gentle one-off warning about hide's use, or the underlying issue, and recommend an upgrade path.

I'd like to flesh out this idea for browser dev tools here for easier collaboration.
