Oh yes, now that is a huge help, isn't it 😂 But, I must say it does suggest and sound like it has a similar goal and point to it as the Windows Experience Feature Pack. Which is to bring things to the OS separately from big updates via WU or immediately something (new) is ready, rather than waiting for things to come via Hs and separating Features from Security & Function stuff.
Things were supposed to soon come via WEFP (or WWEP?) Reading the WWEP article, they sure seem like the same concept.
Here too MS doesn't divulge much, but sure could be talking about either, really. Bit like "same, but different"
Cheers,
