Does Kusama Asset Hub actively accept anything other than Kusama?

Kind of curious because I used to use atomic swaps to buy Kusama (from Polkadot, since there is no other way to do it? Hydration has no options to migrate assets into Kusama), but the pair trading is now inactive.

I can’t access my staking dashboard for Kusama either, nor is it actively registering as staked in a pool, yet it is all available in Asset Hub (staked), no options to claim.

I’m wondering what’s the whole purpose of isolating Kusama in Asset Hub if there is no way of accessing or transferring or swapping anything in there. Is this going to happen to Polkadot too down the line, without working the bugs out?

There are multiple ways of going from DOT to KSM such as:
