Flavouring the isolated systems

[Bicorn]

Do any of the OXPs that add unique details to individual systems deal with the ones that are isolated due to lack of direct witchspace routes?
It feels a little odd if, for example, Oresrati turns out to be a fairly typical system despite being effectively cut off from the rest of GalCop.

[Cholmondely]

As far as I know, no. But I've not done very many of the missions OXPs, which may do something (Xeptatl's Sword, for example).
