Route works fine. We use it in a number of cases where we do monitoring over VPN.
I have not used depends.

I, and several others, have not been able to make DEPENDS work.  I
googled and searched the mailing list, and have found no one who has
been able to make it work as far as I know.  I would love to use the
feature to reduce notifications when a firewall or ISP goes down.

Does such an option/functionality exist?

I provided this example last week to another similar statement:

This works for me:
a.b.c.d    dnscache1.xxxx        # dns=a:www.google.com testip
depends=(dns:UPSTREAMLINK/conn)

(where UPSTREAMLINK is the name of a bb-hosts entry that has a conn check
for our next hop(s)).

If UPSTERAMLINK.conn is red, and the dns test fails, it goed clear instead
of red (well, it can be red for a brief period, so one should alert on red
with DURATION greater than the time your bbtest-net cycle actually takes -
in my case the time taken when DNS is unavailable)

If you have a case where it is not working according to the documentation,
please discuss and file a bug if necessary.

Note though that depends only works for tests run by bbtest-net, AFAIK you
can't have a network check depending on a ports (client data) check, or
have one host checked by one bbtest-net instance depend on a network test
checked by another bbtest-net instance. This is covered in the bb-hosts(5)
coverage for the 'depends' tag.
So, it if isn't working for you, please provide your configuration, and/or 
file a bug.
