Right, that would make sense. I haven't found anything in the snapstats
code which would explain it, the strings are never parsed, they're opaque.

I would suspect the same for the channel "3.0" and "/stable/ubuntu-18.10",
"/stable/ubuntu-19.04" channel names.

So in that case, the proper fix is channel name validation/sanitization in
snapdevicegw, I think?
