Book titles are interesting, but subject to things like house styles.

On the other hand, ad designs are among the most contemporaneous uses of 
text, and I had no problems spotting one with a very prominent capital 
sharp s (image should have been shared on the list, if not stripped).

Use is definitely more prominent than it was at the time (Unicode 5.1) 
that we encoded U+1E9E. Just like adoption of the 1996 orthography has 
not been universal, we can expect there to be a transition period.

However, overly conservative/cautious implementation of software support 
(e.g. using the wrong tables to do uppercasing in a text design app, as 
opposed to for identifiers) will unnecessarily prolong that transition.
