Some wikias are essentially dead (not having received any updates for years or possibly even longer) with maybe a single comment about once a year or so.

They receive almost no traffic at all and whatever they were based on (if there a video game, anime or manga wiki) ended almost a decade ago, which means there is no more room for expansion and they sit idle on the network...

....so is there honestly any point in moving them to the new platform? Since they aren't going to get any new updates even with the setup changed, and in fact would have even less chance of getting updates since the new editor is hard enough to use as is.

For those wikias, there isn't any point in making the switch from Legacy to UCP. because their never going to get any traffic or updates again regardless of the platform they use.

Switching wikias to UCP only makes sense if the wikia is actually still functioning or receiving updates. But for wikia's that aren't then making the change doesn't make sense since they are never going to see any actual use for the new platform as they are still going to be dead either way.
