Template Rights have been updated for version 4.5. You are now able to apply users and groups to a template and specify the specific rights for that user or group.
An additional right listed for templates is the ability to create pages. This is intended for users given the ability to make pages. That user will only be able to see templates that they have been given create pages rights for. In this way you can have users make pages from one template and not others.
Additionally you can now specify display rights for templates. This would allow you, for example, to set anonymous users display rights to no. All pages made from that template would then prevent the anonymous user account or group account from viewing those pages.
Example of Anonymous Group Rights for Template
Example of Content Contributor Group Rights for Template
