I don't speak for the entire developer community-- and we make support decisions together.
Right now there are 14 Piko BLX boards out there that have been used with dRonin--- which is unsurprising because there hasn't been a shipping release yet. Continued support for a target usually comes down to a weighting of: A) is this target significantly different from other targets, is there a robust user community out there for this target (50 or more active boards), C) how hard is this to support, D) how useful is it to the developers?
I've personally found the first-party and cloned Piko boards disappointing because they--- for whatever reason tend to cope very poorly in attitude mode with vibration (I suspect poor reflow/bad solder land pattern for the sensor) .
In short, I don't think Piko is in any short term danger. If, say, a year from now there's still very few used with dRonin, the developers don't use them, and there's other tiny targets supported.... it might be time to start thinking about whether it's worth continued support.
