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?
No, it's not like that at all. The masternode payments code does not belong in the mining software, and should not depend on the mining software. It's making an issue for pool owners where there should be none.
