[theme-reviewers] Posts without Titles

[Philip Walton]

A user, in response to a rejected them, posed this question re: 
smgrundy's review:

Cannot access single-page views of posts without titles from the index.
-> That's good, consistent and how I want it throughout the site. Is 
this mandatory?

I've wondered the same things as well. It's always seemed a little odd 
to me to have the post date link to the post itself. Personally I think 
the date should link to a date page. I know there are other ways to 
create a title-less permalink, but this is the most common.

Still, what is the rationale behind requiring posts with no titles to 
have a permalink to them?
