There were several threads in talk-us during July that discussed the
problems of access=private on driveways:
https://lists.openstreetmap.org/pipermail/talk-us/2020-July/thread.html

   - [Talk-us] access=private on driveways (was: Deleting
   tiger:reviewed=no/addr:street for routes)
   <https://lists.openstreetmap.org/pipermail/talk-us/2020-July/020304.html>
   - [Talk-us] access=private on driveways
   <https://lists.openstreetmap.org/pipermail/talk-us/2020-July/020323.html>

Long story short, if access=private is "added by default", then there is no
way to differentiate between "normal driveways" where uninvited guests
might raise eyebrows due to social convention and actually-signed/gated
driveways that explicitly prohibit access.

If access=private is "added by default" and routers are forced to ignore it
to reach the final destination, then there is no way for them to work out
which routes might actually be allowed conditionally to access the
destination when circumstances are appropriate (deliveries, political
canvassing, invited guests, etc) and which ones truly are prohibited via
signage, barriers, etc.
