I have this at the top of my style since a few days:

#general access:
highway=* & access=( no | private ) {add foot=no; add bicycle=no; add
horse=no; add motorcar=no }

#designated and official treatment:

#allow main users to prevent designated & official blocking them
highway=footway { add foot=yes }
highway=cycleway { add bicycle=yes }
highway=bridleway { add horse=yes }

#set permissions of official & designated:
highway=* & foot=( designated | official ) {set foot=yes; add
bicycle=no; add horse=no }
highway=* & bicycle=( designated | official ) {set bicycle=yes; add
foot=no; add horse=no }
highway=* & horse=( designated | official ) {set horse=yes; add
foot=no; add bicycle=no }

This way, designated & official seem to work correctly and general
access restrictions are also considered.
