To build up a backed and ratified claim to use as a negotiation with the "real" claim holder. This was quite common, get other parties to recognise your claim in order to challenge other claims. It was helpful if those that recognised your claim also had a legitimate claim, but not needed.
That would apply to regions that were never colonized or claimed by anyone. For example, D'Hara claiming to Desert of Silouhettes, and making deals with people to have them all recognize this to put pressure on everyone else to not contest the claim.
Denmyask, though? It seemed pretty obvious the Astrum colony would want it. And Asylon saying "sure, you can have it" doesn't really mean squat as they obviously don't hold any authority over it.
