Is there no plan to allow embedded hostgroups in Nagios?

Once you have this, you would just stick all important windows machines 
in the "Important Windows" group and then nest that group in the general 
"Important" group to achieve the effect of maintaining those hosts in 
only one place, scalable and consistent.

I'm not sure if this is in 3.x or planned, I don't follow the bleeding 
development track too closely...

Short of that, write a script to parse and generate another hostgroups 
file to achieve the same result and have it automated to create the 
Important group from other hostgroups and maintain your hosts in just 
those more specific hostgroups.

I did something similar to auto-generate servicegroups for all tests to 
allow easily grouping them together, you could do something similar for 
hostgroups (my script for servicegroups is released here 
http://www.nagiosexchange.org/cgi-bin/pages/Detailed/2435.html)
