Why can't i just download plugins?

With the rise of the SSD the disc space has become a limited resource. For example on both my machines i have only 200GB of SSD space. Since i have to deal with source built engine (due to dedicated server) in order to download plugins i need to have two identical versions of the engine (source built for coding and official to download plugins). That’s waaay too much disc space and just for nothing. Please give us an alternative way to download plugin source if we’ve already bought them.

Yes, this has been the bane of my existence lately. +1 from me.
