Ok to call WriteUninstaller in .onInit?

Can anything think of negative ramifications of calling WriteUninstaller during .onInit? After looking through documentation and some searching I am unable to find out if this is a bad idea.

Let me know your thoughts.

The uninstaller does whatever you tell it to do, so it can only become a bad idea if you do bad things in your uninstaller. The uninstaller does nothing you don't tell it to. It doesn't write to the registry and doesn't delete files.

Thank you for the response.
