Get Object Types

I am attempting to build my own email notifications and an options page to see when notifications are sent. I would like to allow selection of what object types to send notifications for. Looking at this I found that the object types are hard coded into the inactive class AAL_Notifications and in the class class AAL_Activity_Log_List_Table.

I guess what I am asking for is a feature request that allows getting the list of object types.

I could probably call the method in the notifications class, but I'm afraid to do that.

It appears I would run into a similar issue with actions, but to be honest I'm not too worried about actions at this time. If I want notifications then I'd want them for all actions.

Is my only solution at this time to hard code the object type selection list?
