Imagine 16 different groups all want 1000 GPU's, each decided they want a different type.
Ignoring even the GPU's for a second, somebody has to support programming them (now you get a whole bunch of incompatible GPU toolchains), etc.
Especially for something expected to be long term, it would be stupid to let this happen en masse without at least some different folks sitting down and talking about it, which is red tape.
