I agree to the general premise that we should do more to give information to users rather than the system we have now. That will be improved upon in the near future I guarantee.
On the other hand I do see where @disconsented is coming from. A small search on the forums for “enjin plugin” yields this post as a result. It clearly states that EnjinMinecraftPlugin will be ported over. Also, it is general common sense that one project is not responsible for other projects maintaining compatibility with it. This might have been better asked here. Again common sense that Enjin themselves would be responsible for their own plugin compatibility, he obviously understands the whole plugin to server relationship. Perhaps a better way to ask the questions would have been “Will the existing Enjin plugin be compatible with sponge?” In which we could have replied that “no, but it is planning to be ported”. That would have conveyed a more clear message in my opinion rather than it seeming like he is assuming that the Sponge team will take responsibility for the compatibility of another organization’s plugin.
