To me it seems that making the cutscenes unskibbaple was a knee jerk reaction to a year's long debate/complain about how new players are unable to watch them. If it's that, they can find tune it later and what would be reasonable would be to allow the skipping for preformed parties (be it unsynced or not). After all premade parties already have some leeway on how to perform content, such as no item level restrictions or class restrictions. Want to try savage in party of 8 bards in swimsuits, go for it (it might not be awfully practical though). In such party, the cutscene skipping debate should be social question, not technical one, since it's reasonable to assume everyone taking part into it can be on the same page about which way to go before entering the duty.

The roulette limitation aside, what people ask here is the skipping being possible for premade parties where, again, people can agree between themselves how fast to run.
