Well, as one the primary author of pacemaker once said[1] "Unordered 
and/or uncolocated groups are an abomination."

I don't know if his position has moved but a group beeing a syntaxic 
shortcut for ordering+collocation, trying to make it behave otherwise 
might not be a good idea, even if I understand your need to address a 
group of 40 resources in a command.

Question: the couple seconds (if not a single second) required to start 
synchronously 40 IPaddr2 RA are too long to wait for you ? Why do you 
/must/ start them in parallel ?
