Looks like it finally went live:

LE/PREMIUM V1.12 - December 9, 2016
===================================
New:
- Slimer Mechanism - shut down device if the mechanism is unable to find the home switch.

Fixes:
- pinnode v0.19.8 - Fixed "weak flipper" issue. This bug manifested itself as a weak flipper
if the flipper EOS switch is working only intermittently during gameplay.
- Added family-friendly version of "We came, we saw..." at end of mode.
- Fixed "no playfield lights" issue caused when the Slimer home switch is not working.
- pinnode v0.20.0 (Fixed motor timeout logic).
- Fixed switch alerts for switches that are not on the LE/Premium:
"LEFT RAMP ENTER", "LEFT RAMP 2", "LEFT RAMP 3"

I'm sure the programmers at Stern are kept busy, but I'm continually surprised at the lack of updates. (And I work in software development.) While they do of course move on to new projects after launch, they were also on this long before it became public so it's kind of a wash. Are the frameworks and tooling just not robust? Limited code sharing?

I thought this was a bug, too, but realized I was in a scene. When I completed the scene, the lights were lit. Have you seen this when not in a scene?

It does have more potential but sadly I think it's done except for minor updates.
