[blml] Is ordinary Stayman no longer artificial?

With Stayman, South can also say "North has a hand with which he does 
not want to play 1NT and he wishes to know my majors". Slightly 
different kind of information, but information nevertheless, both in 
information theory and in plain english.

[DALB]

Not really. The former adds almost nothing to South's knowledge of North's
hand; the latter may not even be true.
