Sitecore - Restrict item by Data Template Type on a Field

Question

I would like to restrict the data type of items a user can select on a field. I can do this by Insert Options of tree node in the field's source, but this feels a little open to abuse - say a developer accidentally moves an item of the wrong type under this node then the system falls down. I am possibly over worrying this, but in other CMS I have had the ability to restrict the type of an item a user can select. What is the best way to go about this.

You shouldn't have to worry about developers breaking the source of template fields, this is something that you should prevent your content editors from being able to break though. — Matthew Dresser

For the field types like Treelist or Multilist you can set the source parameter of field with additional parameters like IncludeTemplatesForSelection, e.g.

DataSource=/sitecore/content/home/employees&IncludeTemplatesForSelection=Employee

Here is a post explaining how to use source and here is another one called Tame your Sitecore treelist.
