Personally, I don't require my clients use one version of FileMaker over the other. In fact, I couldn't care less. If they want me to develop in FileMaker 4 or FileMaker 5, I'm as giddy as a school girl to get the opportunity to earn their business. Of course not, what a customer does with their FileMaker files behind closed doors is none of my business. Now, that is not saying FileMaker. will share that opinion.
