the tl;dr: is that wildcards make things annoying and difficult. what's the semantic when a

user:*

would be a top-level subject? what's the semantic when you have

user:*

together with negation (e.g. it's public minus a banlist)? the likely answer in the long run (and this is how the new query planner will handle it) is that you only return concrete subjects, i.e. the concrete IDs that you can definitely say are a part of the result set, ignoring wildcards. that's different enough from the behavior of the current iteration of the endpoint that we haven't gone and made the change yet.
