I'm going to hazard a guess that the exhaustive list is empty. Allowing 3rd parties to launch alien waves to your system puts your existing waves at the mercy of the 3rd party, power or lack thereof from the alien wave may impact operation of other waves.
While it might be different for subsea, especially transoceanic, simply due to market factors, I suspect this is the case on most long-haul routes of consequence. Even the carriers I've talked to who have it productized in their sales catalog with documentation as to the responsibilities of all parties essentially refuse to sell it in practice.
The only traction I've gotten was if I wanted to buy half the C-band spectrum on a new route not yet lit and was willing to sign a very long-term (20 year-ish) contract for it. Essentially it was treated similar to an IRU on half the bandwidth on the route and came lit end-to-end. They were willing/able to do this since they could use red/blue filters and separate VOAs and OPMs to keep things in check at the entry/exit points of the line system. This isn't really practical if you're dealing with just a couple hundred GHz or have frequent need to add/drop it.
