Ok, fine. But what is the magic behind <StIOMaker::Finish> IO: vs <StIOMaker::Finish> StIO:

This fix will be included in #374

I'd simply change it to StIOMaker("StIO" for the fix. It's a bit annoying that makers appear with varying names in some chains for no reason.

It is absolutely fine by me. Please, by all means, go ahead and make changes as you see fit, just don't make us regret we resurrect macros nobody uses or maintains 😃

Okay, okay :)
