Well, I've never found a case or a context where decentralisation and the subsequent federation are not the best option for stability and longevity.
The basic principle to any sustainable and stable model requires sovereignty.
Otherwise it's all a ticking bomb that goes out when the imposed setting displeases too many without them having control over their decisions and context, in which rebellion becomes the necessity to end that cycle.
Without decentralization, it's all a never-ending succession of predictable cycles.
And this is true in literally everything. When power consolidates, it's all a matter of time until a shift in paradigm is required. Because rule is imposed disregarding context. Which is illogical but also inevitable in a centralised construct. This is not necessary when sovereignty is paramount and the individuals can make decisions that fit the context in which they reside.
So, this is isn't any different.
And your idea is perfectly adequate to solve the current problem in online gaming.
This year I had to euthanize a cat I had the pleasure to have in my life for almost 14 years. I saw her come into this world right out of her mum, and I was there when she died. Afterwards, we brought her from the veterinarian and buried her in my mother's backyard.
She had late stage cancer. I never knew when was the right moment to say "it's time". The fucked up part is that we can't get verbal confirmation that "this is it" for them.
She could barely walk or breathe by the end and I didn't know if I was being selfish or if I was stealing time that she still wanted to have. It was brutal. Everyday was just one more day that I wanted to say goodbye.
And then one day I saw her struggle so much to breathe and said "it's time". The meds didn't work anymore and I couldn't ease her suffering in any way anymore.
That moment still sounds far off with your beloved friend. Treasure those cozy and snuggled naps they love to take and be kind to yourself as you navigate it all.
