I'm sure Meris has a smart butt reply about their implementation choices in all of their boxes - notice the radio silence about firmware updates? I guess we just have to choose to deal with them or not, which is something I'm happy about finding after purchase either. At the same time I have gone to far greater lengths (desiging CV control boxes, clever routing) for other pedals before.
The number of other builders going this way (using a flexible TRS connection for MIDI, EXP, Add on buttons, and in the best implementations, Control Voltage) is growing, and honestly, once you begin to use it, it makes sense. Sure, added cost, but most of these pedals live on boards with multiple $300+ pedals and power supplies worth 3-4 times the box cost (well 1-2 times the Meris).
