Could you please have a look at #12498 as well, please?

What's the warning mentioned here? In #12498 I want to move the header()  
before the ob_* calls, as it doesn't work.

There I also proposed a usecase for this function (phpunit).

So have you tested this with BE compression enabled? I'm pretty sure that  
this function will be useless without the header() call for non-CLI mode.

As I currently don't have time to investigate in deepth, I'm unsure - but  
currently I'm for reverting this and really disabling the output  
compression for CLI mode.

Maybe I find time to talk to Michael tomorrow as he's although here at  
T3UXW.
