I also agree that in Dhrupad (& in ICM in general) the microtonal value of the shruti is extermely important but I do not agree at all that chalans and forms are not critical. Chalan is important not just in khyal but also in Dhrupad. Since we're talking about Bhairav, take for example the legendary 18 min recording of Bhairav by Ustad Nasir Aminuddin Dagar - he repeatedly sings the phrase "GmrS" in his alap emphasizing it. I couldn't hear a "mGrS" in it.
There you go making one interpretation gospel.
So is Ravi Shankar's exercise for Bhairav wrong (see above)?
I don't thinks so. Is your exemplary singer wrong? I don't thinks so.
He is entitled to sing however he wants in his Dhrupad alaap providing he sticks to the Bhairav microtones.
One can make a rule about how certain singers or certain groups (gharanas) interpret something but not about limiting the interpretation of a raga universally. And your argument about demonstrating a formal rule from phenomenon heard in an alaap section (such sections, being by definition, free form) is self defeating.
