To a 1925 (99 years ago) military force, the Diego Garcia airfield would have had zero importance.
I bet that's what the UK thought about Hong Kong in the late 1800s, but when 1996 rolled around I think they (and many HKers) would have liked a longer-and-99-years lease.
While geography isn't quite destiny, it is fairly important, and having a random rock in a place where there are no other rocks will always be useful IMHO (unless we perhaps develop teleportation).
"Of over 13,000 islands examined, approximately 12% experienced significant shifts in shoreline positions. The total shoreline length of these islands approaches 200,000 km, with 7.57% showing signs of landward erosion and 6.05% expanding seaward. Human activities, particularly reclamation and land filling, were identified as primary drivers of local shoreline transformations, while natural factors have a comparatively minor impact. "
My guess is that by carbon sequestering and/or SO2 injection in the stratosphere, the climate change will be controllable within a few decades.

And timespans are like that for climate too, millions of years not 299
We can choose to mitigate the change or make it worse for ourselves.

Mauritius is not China. Not that I am suggesting for this to happen, but what are they going to do if the UK just decides not to leave after 99 years?
Close to Africa/ME: Maldives, Seychelles, Comoros, Mayotte
Close to SE Asia: Cocos and Christmas Island
Diego Garcia just happened to be forcibly depopulated by the British, so was a convenient choice.

That's the whole point of Diego Garcia: It's not "close to" anywhere, and it's nearly in the middle of a bunch of places. That's what give it its strategic importance.If Diego Garcia were no longer an option, there would be alternatives. Especially with US levels of lease money.
That said, few of them are quite as remote as Diego Garcia. Which means not quite as easy to secretly fly RQ-180s or whatever the hell is more clandestinely based there.
Remember that the small islands don't have much land to begin with, and bases are large.
