Deleting: DSEs require CDTs, CDTs are not recommended, so now what?

Question

I have a read only grid with select boxes enabled creating something like this Almost everyone says that you should used delete from data store entities to handle record deleting. 
 However, this page https://docs.appian.com/suite/help/23.1/Custom_Data_Types.html says that most of the time you should not use CDT but CDTs are required for DSE. Where can I find a step by step walk though that does not use CDTs or DSEs to delete multiple records from a read only grid?

 This is strictly referring to when you're building out Synced Records, i.e. Record Type Data , which is the "newer" approach Appian now recommends (but which, so far, most existing implementations don't use, or are only just starting to experiment with). 
 If you are using Synced Records for your data already, then you'll want to look into using the Delete Records smart service.
