Instead of requiring reader to follow link to learn what the state of support is
this could just briefly summarize it and reader can then choose to follow link
for the details. Does not need to be detailed itself, that is what the link is for,
just a small change would already help a lot, for example:
"details the state of 32-bit x86 support." -> "details reduced 32-bit x86 support."
