Let's try to make an analogy.
What's the difference betwen p2pool1,p2pool2,p2pool+ltc+segwit and bittorrent,utorrent or bitlord?
Is that you can change the torrent client and you don't loose your file.But you can't change p2pool chain without loosing
your work.
So don't play with miners work and time.
Pool operators should be interventive people,open to new ideias and forks and not open to caos.
Part of running a p2pool node is choosing your bitcoin node software, optimizing your node, and signaling your support for different BIPs when your node finds a block. When there is more than one p2pool sharechain, you also get to choose which one your node joins. If you are not running a node, you do not get a vote. If you do not like it, go to a regular pool. Quit trolling.
ATTENTION:no trolling intention,only helping.
About your answer although you are not the OP.
What's the point of runinng a node if you are afraid of mining on it?
Take a good look, there's a lot of empty nodes at this moment!
