Multipools support so many coins, and every coin has their way of doing things, and we already have such a huge headache from avoiding forks, mandatory updates (across 40 wallets!!) that when a coin comes along and is like "Hey now you also need custom code, or a stratum update" it throws quiet the fork in to our operations. We don't follow your coins directly (at least I don't) but we are more than happy to comply and make sure your eco system is working-- just make it easy and clear for us to do so, because we have to do it across MANY MANY coins every day.
That's like complaining that you run a travel agency and each airline has different policies and keeping up with them is SUCH a burden. I mean, isn't it kind of obvious that dealing with dozens of coins is going to be challenging?
