Glossy refraction in thin mode - How?

I was surprised to find that refraction glossiness doesn’t work in thin mode, because AFAIK glossiness defines only how much ray will scatter upon entering media and will not affect by travelled distance, right? So why it couldn’t work in thin mode?

Is there some workaround? How to make transparent blurry material without using actual refraction?

Wow, how simple is that. Why i couldn’t figure it by myself? :] I thought that IOR - 1 is exactly the same as thin mode on. Thank you!
