Further hide deprecated versions in version listing
An unfortunate consequence of an accidental upload of a nightly ghc lib to hackage:
It would be nice if we could set hackage to make deprecated versions much more hidden -- i.e. perhaps not listed directly in that section at all, but just hidden behind a link...
In a <del> tag maybe? A strikethrough is more noticeable than a slight change of color
I'd prefer deprecated versions hidden behind one more link or a collapsible section on that page.
Accidental upload is why e.g. cabal have changed to upload candidates by default. I'd be ok to require human click to publish packages. (amazonka monster uploads is a bit of chore to click through then, but OTOH, if mistake is made in automatic upload there, it's a major mistake).
Note: solver is free to pick up deprecated packages! it's a soft preference. To "completely" prevent a package version from being used, you'd need to make a revision with unsatisfiable constraint (like base <0), but even that is not enough, as if package makes through into e.g. stackage nightly snapshot, they pin revisions, so even if a package versions is later deprecated or/and revised, it will still be in that snapshot (that's the point of snapshotting).
It would be very confusing if version doesn't appear, or is hidden.
I'm in favor of <del> or/and semantic markup, accessibility should be a top priority for sites like Hackage.
EDIT: Note that versions with unsatisfiable constraints (which are numerous) dont' have any visual clue in the version listing. They could.
