Most of this is a legacy of the old "extmod" design where you could load _some_ extensions dynamically but only if the server had been built with support for them in the first place. Note that since we now only initialize the DPMS extension if at least one screen supports it, we no longer need DPMSCapableFlag: if it would be false, we would never read its value.
