We don't know, but (and I believe this to be the case) if the developers are not petulant children arguing on a forum such as this, then its likely that their discussion will revolve around finding the common ground in between opposing opinions. That would be a more interesting discussion to be having but all I see every day are polarised opinions (presented as fact). Exaggeration by both camps, hostility, refusal to move from entrenched positions and mischarecterisation of others views.
Maybe you're not looking hard enough?
