I recall reading that experienced readers recognize word shapes, which 
is why lowercase words with their distinctive outliers (ascenders and 
descenders) are easier to read. Because of the baseline, I would not be 
surprised to find indeed the upper part of the envelope, particularly 
for capitals, contributes more distinctive features.
A glyph that, while not disrupting even type color and rhythm, adds some 
distinctiveness to the upper envelope may contribute to readability.
Ultimately, one needs to put different designs to the test, as I doubt 
that readability of individual features can be predicted. 
Non-typographers, but native readers, would make good test subjects for 
readability, while the typographers would have an advantage in proposing 
designs and getting the other details right.
The shape that should go into the Standard, should be the one that is 
most appropriate for a Times-like style. The decision of what that is, 
does not rest with any one individual (as someone here claimed), but 
should represent a consensus of the community. In reaching this 
consensus, readability should be one concern, which will feed back into 
some of the design's features (but probably not all).
This does not mean that the glyph is then 'standardized' and frozen, but 
the expectation would be that typographers designing closely related 
typestyles would create designs for the glyph that would be a continuum 
around the representative glyph, rather than isolating it by 
collectively all designing their type on a different concept.
