The level does not conclude with a Chapter Complete screen or something equivalent to that, which is generally where we draw the line when adding ILs for custom maps since we use that screen to review a lot of things relevant to verification (map version, Everest version, game version, presence of assist/variants/extended variants, final time, etc). In a more meta sense, it's also not tracked in the journal as an IL since it's marked as an Interlude internally (same as vanilla Prologue and Epilogue), so going by "game/designer logic" it doesn't really count as an IL either.
We've seen interest for it as an IL in the past and it certainly doesn't lack gameplay, so I'm sure we'd be open to adding it if the above factors were to change, but as it stands there's unfortunately no way for us to create a leaderboard for it.
Due to frequent minor updates to the map-pack, submissions no longer need to be played on the most current patch. Instead, we will now accept submissions from all 4.0+ patches. This ruling may be revisited in the future if we are given reason to do so.
