Playing with fire writing to the Windows Installer's private data but I don't have other ideas if old chainer doesn't have a sharing mechanism.

Hello, we are migrating from another chained MSI installation (in fact we used ISChainer, but I do not think that matters) to Burn. There are several bundles that may be installed in parallel and that share some of their packages. With WiX 3.9R2, the dependencies among these Burn bundles are treated well without extra coding. I.e. I install Bundle1 and Bundle2 that both contain a SharedProduct, than I uninstall one of the bundles, and the shared product remains. However, we also have to treat the use case that an "old-style" chained installation and a Burn bundle coexist. Is there a built-in way (with or without using the Dependency extension) to handle such dependencies? In the "old-style" chain, we mimic Burn's dependency-keeping behaviour by a dummy "flag" component in the root of the chain that is installed if the associated chained package is installed and an uninstall condition for the chained product that inhibits uninstallation if this component has other clients (Uninstall if $GUID=2) Our current approach to build the bridge between the old and the new chain is that the CustomBA adds a new value to the component entry under HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Installer\UserData\S-1-5-18\Components\<CompressedComponentGUID> for the "flag" component and removes it again on uninstallation, so that uninstallation of the "old-style" chain will not remove the product. I know that this is ugly, but I do not see another solution. On uninstallation, the CustomBA also looks whether the flag component is still used by other products to determine whether to uninstall the shared product.
