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.
It could be a mere informative reference: "the most-community-accepted
libraries at the time of publication are:".
Keep in mind also that some of the libraries change irrevocably (like
base has; with changes like Unicode I/O, or adding the Category class
above Arrow. When it is tied to a particular compiler version it's less
trivial to support multiple libraries... or even when it's not, version
skew can get annoying
