Can you update the PR description to explain whether you checked the page for any info that might be beneficial to preserve since it doesn't exist anywhere else on the site. I can't go through all of them but at a glance some of these warrant at least a single sentence added to their relevant corresponding pages, e.g. Why are generics covariant? probably deserves a mention on the generics page, something about AOT vs JIT tradeoffs on the dart compile page, etc.

@MaryaBelanger : I did in part. Maybe removal isn't the right move here. I'll take another look.

I think until someone has a chance to collect (today's) common questions and determine their answers, I think it's fine to delete this. It's one of the least visited pages.

It's just someone needs to go through each answer to determine if it is still relevant and if so, should it be documented elsewhere? Some cases, such as in the browser version support change you already made, already should have been. Other answers, even if they're still relevant, might already be documented elsewhere or not important enough to document.

I'm happy to discuss any of the entries if needed :)

@parlough @MaryaBelanger : I did discuss with @munificent and his views matched @parlough . I moved some information, but didn't do all of it yet. @MaryaBelanger : Would you prefer to have a full accounting first or can I remove and we can revisit after I/O?
