Should we support all the old /browse/*" pages

[kaste]

I don't know if we should use "browse/new" at some point instead of our "/?sortyBy=..." or if we should at least add redirects for the browse/* namespace.

We have all the "browse/*" pages except "Author Hall of Fame" and "Trending".
We've added "/libraries", which could be "browse/libraries" as well.

We've added "/libraries", which could be "browse/libraries" as well.

Treating libraries separately from packages makes more sense to me since all other /browse pages only cover packages. If library-specific "browse" pages were to be added, we'd need to think of something, but I certainly wouldn't move the main libraries page under /browse.

IMO the features from "browse" that we want are all there (except perhaps "Author Hall of Fame", which I don't care much for personally), and much improved because they're integrated into the search functionality. I don't think we need to follow the page and URL layout of the old site at all, I think ours is in many ways better. But we could make some a bit easier to find (like you just did by making "newest" and "recently updated" clickable).
If we'd do it for feature-completeness of compatibility's sake, we could add redirects from "browse" to our equivalent. I'm just not really sure who would meaningfully benefit from that. Maybe some minor SEO benefit if Will does ever hand over pc.io to HQ, but for me, by now, that's an entirely hypothetical scenario.
