Having looked at the code, the query in question is definitely a hefty one.
I’ve looked at ways of optimizing it and all that, as have I’m sure people smarter than I. I’m sure it’s doable, but it’s a matter of how much time it would take and how much of the rest of the codebase would need to change.
No rush, as I realize we all enjoy this community for free, but is there an update on the plan to get it fixed? I (and I’m sure others) would be happy to help out in whatever way we could.
