It’s to prevent lag. Buying an island expansion upgrades the hopper and spawner limit on your island I believe. Anyways no support, it’s designed to reduce lag and by implementing this would be bad for the server. Sorry.
There is a suggestion to increase the hopper limit already but as it stands it will not be completely removed
I would support a higher hopper limit as Borahae suggested, but removing is completely would be a no go.
Sorry, I can't support fully removing the limit as hundreds if not thousands of hoppers could crush performance. That said, I recently created a thread suggesting a modest increase: Skyblock Official Site | Skyblock
Doesn't the limit go higher when you buy expansions? I think it's better this way because it gets way too laggy if there's so many of them on your island
Assuming you have a max expanded island and half your hoppers are tied up in shops and machines and such, then you'd be able to sort at most 16 items, which isn't super useful.
