Short update on that; I asked Adam Langley from Google via Twitter
yesterday why Chrome does not support a stronger HMAC. He pointed out
that AES-CBC mode is still susceptible to the Lucky13 Attack, which I -
to be honest - totally forgot about.  So your concern is valid.

What I don't understand is why your Chrome did not negotiate for
AES-GCM. On which platform are you testing this (OS and architecture)?
