Are there griefs it protects against that GP does not? If so, please elaborate, because I have something to address.
Doubtful, but maybe. More likely I’ll just prevent overlap. From an anti-grief standpoint, WG is hugely bloated (and it requires an entirely non-anti-grief WorldEdit as well). Making GP a front-end for WG would require everyone who wants to use GP to also get WG and WE, and WG includes many features that aren’t necessary for anti-grief. So that change would be a negative for ease of use, and a negative for efficiency (or positive for “bloat”, but I that’s a dirty word I don’t like to use). There may be some positives - I’ll wait and see what Nentify’s response is regarding specific actions WG protects against that GP doesn’t.
I do understand that sometimes server owners want some of WG features in their world along with GP, and that’s why I do intend to make it easier to run both on the same server together. I’ll do that by not allowing GP claims to overlap WG regions, and vice-versa.
I think you may be overstating the situation - based on my conversations with sk89q, I think mods will continue to be a huge anti-grief problem for sponge, just like they were in classic Tekkit. He seems unwilling to push for a requirement to force all plugins/mods to ask anti-grief before they make changes, so sloppy plugin/mod authors will be accidentally creating tools for griefers to use, which plugins like WG and GP won’t be able to stop.
