You are right that this may not be as exciting for some but I believe even if you do not care about ethereum this is still good news. Ethereum ETF has long been approved but staked ETF has not yet been until today. So, this simply means we are getting progress.
XRP ETF could also be approved soon so it is definitely a good time for altcoin investors as this might be the well anticipated altcoin season as bitcoin's price dwindles down.
Although, it's just an acknowledgement not fully approved but it's a good good news to Ethereum and altcoins investors as it seem to strengthen the market stability of atlcoin. However, it may or may not have significant impact to the future potentials of Ethereum and altcoins because if we corelate this to when Trump proposed to insert Bitcoin into US strategies reserve investors where optimistic that Trump administration will maximize the potential of Bitcoin but till date Trump administration has not made any policy in regard to his proposal for Bitcoin as US strategies reserve.
