Unfortunately, it _may_ not work.

tsitc> grep -i depend /usr/local/nagios/etc/nagios.cfg
# Set 'soft_state_dependencies' option for _via_provider checks (these 
depend
# should not give false positives if the dependencies are in soft 
states).
cfg_file=/usr/local/nagios/etc/dependencies.cfg
# SOFT SERVICE DEPENDENCIES
# This option determines whether or not Nagios will use soft service 
state information when checking service dependencies.
# Normally Nagios will only use the latest hard service state when 
checking dependencies.
soft_state_dependencies=1
tsitc>

Even with this set, the boundary case is for A <= B (service A relies on
B; B is a dependency): if B has failed but has not been checked and
therefore detected as failed - whether a hard or soft failure, then the
service check of A will be handled as it would if there were _no_
dependency.

Other than a test bench set up, it is is not clear to me how to proceed 
furher.

Yours sincerely.
