You are right, compaction (can) generates homogeneity problems.
Personally, I use expansion most of the time.

For porosity in subdomains : yes, it is interesting. This is one of the 
things I have put in the triangulation package (also computes fabric, 
stress, strain, coordination number, etc. in subdomains).
