Makes sense to me.  I've thought about doing the same, when I look at  
my attrs
files that have 30 attributes listed, most of which are *= ANY values.

I'd make one change, and that's make it more obvious what the config  
is doing:

    defaultaction = drop | allow

With the default being drop so that it maintains backwards
