This illustrates the difficulty of maintaining a separation between bugs and discussions:

> To be clear, I 100% believe that there is some kind of leak affecting some specific configuration of users

In this case it seems you believe a bug exists, but it isn't sufficiently well-understood and actionable to graduate to the bug tracker.

But the threshold of well-understood and actionable is fuzzy and subjective. Most bugs, in my experience, start with some amount of investigative work, and are actionable in the sense that some concrete steps would further the investigation, but full understanding is not achieved until very late in the game, around the time I am prototyping a fix.

Similarly the line between bug and feature request is often unclear. If the product breaks in specific configuration X, is it a bug, or a request to add support for configuration X?

I find it easier to have a single place for issue discussion at all stages of understanding or actionability, so that we don't have to worry about distinctions like this that feel a bit arbitrary.
