Comment (by jhpalmieri):

 I'm sorry, I'm confused again. Are you just proposing the changes in the
 branch, or also to remove files from the server? It's important that
 commands like `sage --optional` still list the old-style packages. If you
 actually remove them from the server, that won't happen, right?

 {{{
 $ sage -i p_group_cohomology
 Attempting to download package p_group_cohomology
 Error: could not find a package matching p_group_cohomology
        Try 'sage --package list' to see the available packages
        There is no package similar to p_group_cohomology
 }}}
 Then since `sage --package list` doesn't actually list
 `p_group_cohomology`, it is not clear how someone is supposed to find out
 about it or find its URL. `sage --optional` does list it, but doesn't say
 how to obtain it. If I were a novice user, I would be confused about
 whether this was a valid package or not.

 It might be better if, instead of deleting item 2b, it behaved
 differently: it should never install a package, but only print a warning,
 something like: "Old-style Sage package available from <URL>. Run <CMD> to
 install it. Only do this if you know what you're doing." In addition, it
 should print the apropos message (probably first), so someone running
 `sage -i python` will be given appropriate advice.
