I think I understand the component state approach but I am not sure this is
possible with the current implementation of custom tables as I can't see how
they can be associated with a component.

There is a helper function in wcautil that is usually a tell tale sign
you've found the code ::WcaGetComponentToDo(). The old school way (most
of serverca uses the old school) is to call
WcaIsInstalling()/WcaIsReInstalling()/WcaIsUninstalling() to determine
the scheduling. WcaGetComponentToDo() is a nice wrapper that cleans up
much of the confusion.
Using conditions to control your CustomAction install/uninstall
behaviors is primitive and usually insufficient... but the most
visible. Data driven CustomActions that modify machine state via
Resources should really use Component states. That matches the design
of the Windows Installer.
