Seedling kumquat trees have a built-in advantage in that if they ever freeze to the ground they can come back the same fruit. Whereas when grafted it would come back as whatever the rootstock was. Own-rooted citrus has the same advantage. I knew a man in central Florida who propagated own-rooted citrus trees in the 1980's and early 1990's. He sold a lot of it to GA citrus growers.

In at least some citrus, the apomictic seedlings are thornless, while the sexually produced seedlings have thorns.  I grew out seedlings of a Poncirus trifoliata x Pommelo hybrid and all were thornless.  The hybrid was one from Florida which had proven a dead end in breeding because it would produce nothing but apomictic seedlings.

I believe that they will produce apomictic seeds as you describe for mango, at least that's what I think citrus does. Apomictic seedlings also must go through a juvenile phase before beginning to bear fruit, just as sexual seedlings must.
