People are arguing at cross-purposes. One faction is arguing that dragonboobs can be justified in the setting with arguments ranging from "Dragonborn are egg-laying mammals so they should have breasts" to "there are more unlikely things in the world that are accepted so dragonboobs are okay."
The other faction is arguing that the dragonboobs were added purely because the designers thought a female race must have pronounced breasts to be (a) female and (b) attractive to play as a race for female players and (c) the role-playing challenges of a gender-indistinguishable female character were too much for the players.
Both arguments are right, and neither argument pertains to the other. In particular, using the first argument as a counter to the second does not make sense.
And for the record, I think regardless of whether dragonboobs can be rationalised they are initially strongly counter-intuitive and thus damage suspension of disbelief. Also, you lose out on role-playing opportunities when you eliminate interesting distinctions between races. A species that outsiders can't generally tell whether a member is male or female (they have +2 Strength as well, remember), is a small but interesting detail to a campaign.
