"process-committed administrators" are not conservatives. They just want you to stick to policy. You are of course free to change that policy by the normal root. Discusion to hammer out a soild policy suggestion. Presenting it to anyone who cares to try and gain a consensus and perhaps some further modification in order to do so. Then depending on the level of support either institute it or hold a final vote to see if you can get enough support to do so.
Is it just me, or would things go a lot better if experimentation was part of the policymaking process? This is what Proposed Deletions is doing and it seems like a far better idea than arguing ad infinitum about improving our deletion processes.
