Should Gondor have given Calenardhon to the Dunlendings?

[Findegil]

Those Northerners had saved Gondor and, although they were not Numenorean, it could be said that they might have ancestors who had be elf-friends in The First Age, and, therefore, almost as superior as Gondorians.

But the same is true for the Dunlandings, even so the Gondorians did not recognise it because they spoke a langued that was related to that of folk of Berthil in First Age.
