I'm posting this back to the list.  I prefer my Wix discussions to be shared.

I am aware of them, but I have not had a scenario where I have chosen to use 
them, yet.

Conceptually, it requires carefully embedding debug code in your working 
immediate custom actions that is triggered only when the mutating variable is 
set to certain values.  The part about embedding debugging code into my custom 
actions is a little scary.  But having an immediate custom action complex 
enough to require several different run scenarios is also scary.

I think the need for using mutations can be avoided by making ones immediate 
custom actions modular enough that they can easily be tested in a linear way.  
Put another way, if you think you need mutations, maybe you really need to make 
your custom actions narrower and more modular first.  Really complex immediate 
custom actions that touch more than a few properties are hard to test anyway.
