There is slightly more to it than just giving them different names,
you'd also have to make sure they don't have any file paths in common.
Also, if both packages provide docs then one should have precedence
over the other.
Also, a practical issue is that `cblrepo` isn't able to handle more
than a single version of each package in its database.

What would the purpose of providing two versions of some packages be?
Just to tick the has-haskell-platform box, or is there more value to
What packages should be built using the -hp packages? If any, should
we try to do anything to avoid the diamond dependency problem?

Most software today is very much like an Egyptian pyramid with
millions of bricks piled on top of each other, with no structural
integrity, but just done by brute force and thousands of slaves.
