If I understand that correctly, this would mean to simply include the
particular version of a library that happens to be the current one at
the report deadline. In other words, the report specifies that say
version 4.1.0.0 of the base library is the standard one for 2010.

Since old library versions are archived on hackage, this looks like a
cheap and easy solution to me. It's more an embellishment of alternative
1. than a genuine 3.
