Trim in RAID 0 using Intel RST on Windows 8 and 10

I notice the following comment in the description of the Intel® Solid-State Drive Toolbox:

Optimize the performance of an Intel SSD in RAID 0 using Trim functionality Intel® Rapid Storage Technology (Intel® RST) 11.0 or greater.

     NOTE: Trim on RAID 0 is not supported on Windows 8* or Windows Server 2012*

Is this a temporary situation? What about on Windows 10? I thought it was generally agreed that Trim was pretty important to keep write amplification down thus maintaining high performance and extending the lifetime?
