No, SPL nodes will be specific towards Splinterlands and SPS governance. It will also be different software compared to GLS.
That means, if you want to run a node for SPL, but then switch to GLS, you'd need to switch the software from SPL to GLS, and also make sure you switch the licenses as well.
However, since the Node software will be generic, I think the process will be very simple.
Thank you for clarification.
