I thought about this a bit more and I think is at most nice-to-have.

Extensions and ReaScripts should have proper error reporting anyway if the running REAPER version is not high enough, because they might be installed manually or via ReaPack.

Also, larger extensions/ReaScripts sometimes have features that work in some REAPER version and other features that don't. That couldn't be easily covered by a simplistic scheme.

One useful thing about having REAPER version numbers in the recipe could be to actively recommend the user to update REAPER if the currently installed version is not high enough. This would be a nice convenience feature and save affected users a few mouse clicks. Let's see.
