Given that the premise of this discussion is how Tiny11 credits removing WinSXS as part of the reason they were able to free up the memory, it would appear the article (and OP) disagree.
The article talks about memory savings and storage savings. Removing WinSXS is a storage savings play, not a memory savings play.
Here's the relevant quote:
> Moreover, removing the Windows Component Store (WinSxS), which is responsible for a fair degree of Tiny11’s compactness, means that installing new features or languages isn’t possible.
There's no need, which is why it doesn't.
