the logic; anything you do to reduce problems or to prevent problems 
connecting to SSL sites because
of slow OCSP servers or similar reduces security itself ...

yes and no, but faking a valid OCSP response that says good instead of 
revoked is also possible ...

the primary reason was to prevent problems for connection problems - or 
whatever problems - in connection with the OCSP

maybe; but Heartbleed showed us something different ...;

of course; if there would be only one CA, and there would be only SSL, 
this CA would know what hosts you connect in your browser, because of 
OCSP ...

but the privacy concerns in this connections is less than the tracking 
cookies where a little bit more of information is sent ...

certificate and what time)
