Personally I've wanted a 1-page IEEE publication for a while that accepts smaller contributions, where people can share these kinds of insights. Just a "we tried this, this is what happened" or "we were not able to repeat this" or "we found this interesting, but we need more data".
You could argue it's kind of like a long abstract, but a long abstract really indicates you intend to probe it further, but in actual fact you might just want to indicate that there might be something there for somebody else.
