Is #3 particularly useful/necessary?

Australian television stations are appalling for running late. One
station in particular routinely runs 15-20 minutes late due to live
reality television programs (even though they know this always happen
and could schedule for it).

I'm abusing post-roll by setting it to 20 minutes. This works as poor
man's soft scheduling so far. In my case I could put a hard 20 minutes
on every program as I have three tuners and would probably never get a
conflict. Currently my third tuner only does about 1 hour a week.

However, most Australian users would not (we only have 5 OTA stations 
so 3 tuners is excessive); hard extra time would cause conflicts, while
post-roll allows for best effort. Programs are rarely repeated here
so a conflict is a missed program.

Of course I'm really arguing for the soft scheduler, which would be
great for Australians. (I've even glanced at the scheduler code in the 
past but found it a bit daunting to start working on this though.) 
However I think your interim solution would actually make things worse.
