Chrome Tabs questionm whats your expirience.?

I want to know whats the problem with that component. Why is it expermiental. Normaly there can be some problems with an expermiental component. I like it more as the web viewer but i am afriad tat there are some troubles with that. Which Andorid Version is needed that the App can run with that Component. Because if i you need API level 24 i know that i will not have much user because the mostly Android Levels are less than 24. Whats you expirience with Chome TABS?
