For delegation itself, in practice, it’s very difficult for delegates to receive delegation as Delegation remains low and Delegators haven’t been re shuffle delegations effectively. For example, there are several top delegates who haven’t voted for more than a year and in theory, delegators should re delegate but due to various reasons including legal and logistics, they are not so keen on it.
So most of recent delegations have been from either Uniswap DAO treasury or some from the Uniswap Foundation. There’s new cycle of delegation from DAO treasury that’s in RFC phase, but this in practice, is likely to require previous voting history. https://gov.uniswap.org/t/rfc-treasury-delegation-round-2/25355/10
