We aim to remove our usage of Object.observe in a future release. To future-proof your code, I would suggest you to use the array mutation methods of Polymer to modify arrays such as grid.columns.

For example:

// With Object.observe
grid.columns.push({...});

// With Polymer array mutation method
grid.push('columns', {...});

Fortunately vaadin-grid contains a polyfill, which will be used after Chrome removes the method. So it will not break any existing functionality. Already verified this by testing in Chrome Canary.

Now that Chrome has removed this API, and the polyfill is less than great (consumes a lot of CPU), we need to drop the support for the current columns API.

As a heads-up, the current plan is to remove it in a minor version, 1.1 probably.
