Do you know who offers more? I deliberately chose Yubikey as example as their limit was the highest. Others like Nitrokey etc. support even less.

Even if there are keys that offer more, the number 1 brand in hardware keys having that limit is not a good look if the idea is to transfer 'everything' to it.
