Invariant Country on Patches

Ok so I am setting up our PROD NS 7.1 and setting up the patches we had in NS6.

Someone on my team mentioned to not check off the invariant country to save space and have those parts of the patch not replicate out to our site servers.

Is this a good practice? I hit a patch.. MS12-071 that is an IE9 patch and only has Invariant Country patches... Searching here I saw someone post

"This is the normal behavior for Office 2007/Vista/Server 2008 updates; the patches are language-independent almost always."

We do not patch office.. so with that does that mean I need to leave Invariant Patches checked for Vista and Server 2008?

Thanks!
