ERC-8056 is a great way to preserve composability and liquidity through a stock split.
The alternative is issuing a new token and airdropping it to beneficial owners (something
@merkl_xyz can do), but then you'd have to migrate liquidity and existing markets, which is painful.
That said, I don't think it's a panacea when it comes to dividends.
Distributing a dividend through ERC-8056 effectively means buying back shares of the SPV that issues the tokenized share, which raises the exchange rate between the token and the underlying security.
Tokens whose value diverges from the underlying are inelegant (even if oracles handle it), but the bigger issue is that it forces everyone to reinvest the dividend. That's not how tradfi works, so why not leave people the choice when the tradfi UX is easy to preserve?
For splits there's genuinely something to protect with ERC-8056. For dividends, tools like
@merkl_xyz can pay beneficial owners directly, even several layers deep into composability, since Merkl can always identify them. So the standard isn't a necessity there.
