You maintenance idea is a good one of disabling a certain hook, importing, 
enabling the hook again.

Globally turning off all hooks or for certain stems is a little chaotic, 
since how do you know you want ALL hooks off, and not just some.  So we don’t 
have that feature in Grouper.

Some other suggestions:

1. Your hook can decide if it needs to act... it could see if the gid 
attribute is there, and if so, don’t reset it.  Or is there a reason this 
wont work?

2. Your hook could easily read a custom Boolean property in the 
grouper.properties which would tell it whether or not to act

3. Your hook could easily read a string property in the grouper.properties 
which tells it if certain stems prefixes are excluded

4. If you are doing the import via Java, you could set a threadlocal in your 
hook which tells it not to act, then unset when done

Let me know if you want to do any of those, I could send you some code 
snippets to make it easy

Regards,
Chris
