TexLive distributes collections of macros, not  packages separately,
they make their packaging based on CTAN. In the meantime CTAN packages
are not versioned, they only have internal release number, no tags,
releases and so on, see [1].

I also fail to see what problem you try to solve when suggest fetching
macros from CTAN, you are going to have the same amount of data mirrored
as a result.
