I would like to suggest setting the permissions for /version and /plugins to OP by default.
I see plenty of server owners not realizing these commands have permissions and they can simple negate them in their permission manager, due to that, people keep making these janky "no plugins" plugins.

Most servers seem to want to hide their plugins whether It be for "security" reasons (this is what they say, not me) usually due to anti-cheats, or they simply just feel like its part of the mystery of the server.

That said, these two commands really shouldn't be left in the players hands. Its really none of their business what plugins you're running and/or which server software/version you're running.

I think setting these two commands to OP by default will benefit a lot of servers, allow them not no longer have to worry about who can see this info. Plus OPs can still use the commands, as well as the permission can be added to the appropriate players, ie: admins.

Thanks for your consideration
