No. Never do this.
Selectors are an operational convenience for key rotation and
ease of domain delegation. They have no semantics beyond
being used to query DNS to find the public key.
Sure. That's the right answer from a standard POV, but if I can extract
statistically significant information by segregating mail streams by selector,
I'll do it anyway, I don't care what the standard says (no, I haven't done
this analysis yet, so I don't have an opinion on if one actually could do it
or not).
