Is there a way to make the modal window that pops up from the CREATE PAGE button on the Control Panel NOT show all the templates?

When I pass this site to a client, I'd like them to only be able to create a single type of page and to not confuse them by showing the other options.

Update: I just found that the default fieldset called user.yaml has a field called "hide: true" and this user.yaml page does not show up in the selections from the CREATE PAGE button.

When I add "hide:true" to other fieldsets it also hides them from the CREATE PAGE button.

So, is this the best solution or does hide:true also do something else?

Is there anything else I should be aware about when using the hide:true option on a fieldset?
