I do not think its an issue at all, at least from a gen owner point of view.
For most if not all of my current APs (I do not wish to name the current number here but lets just say its sizable), I do not see the need to change the straps for any of them. I think that the color theme, dial and material of the watches are much more significant factors when it comes to the appeal of any AP watch, with strap choices being a distant secondary factor. The watches themselves mostly contain enough features to keep the owners attracted.
The strap choices for the quick-change enabled 42 and 43mm ROOs are limited somewhat but they are still appealing enough for anyone who will buy the watch. Overall though, the 43mm ROOs do not do as well as the 42mm due to their chunkiness and the overall market trend moving away from watches of such proportions. This was why AP discontinued the 44mms in favor of the 43mm, and why the 48mm ROOs (T3, Shaq, Legacy for example) were discontinued years ago.
