This is similar to the feedback you've already received about this issue in feedback item 331910. The installer blocks SQL installations in geographically dispersed cluster because geographically dispersed clusters REQUIRE that the cluster disk resources have dependencies on "other" resources that control access to the disks.
The installer should not be so picky about the cluster disk dependencies. Worry about setting up SQL dependencies and let the cluster admins worry about setting disk configurations.
This issue causes unnecessary support calls to both Microsoft and to geographically dispersed cluster vendors
