Is it safe to use the bigalloc feature in the case of ext4 filesystem?

In the man ext4(5) we can read the following:

    Warning: The bigalloc feature is still under development, 
    and may not be fully supported with your kernel or may 
    have various bugs. Please see the web page 
    http://ext4.wiki.kernel.org/index.php/Bigalloc for details. 
    May clash with delayed allocation (see nodelalloc mount 
    option).

According to the link above, the info is dated back to 2013, 
which is a little bit ancient.

What's the current status of the feature? Is it safe to use 
bigalloc on several TiB hard disks where only big files will be 
stored?
