Thanks for the reply. This makes perfect sense, and is what I'd try to do, when available.

It's very good to know that there is a willingness to add, but that approach is not a panacea. Adding to a current project requires hacking the existing installation and hopes that the hack will be applied the same to future versions of WP. And there's the necessary time consuming political process of convincing people that there is a really such a need.

Also, there are likely to be a very large number of needs for a more specific filter and adding more and more hooks would cause serious bloat. Whatever the current list of available hooks is at best always a balance.  

What I was hoping for was a robust way to identify the current context so that there isn't a need to go adding more hooks all the time.
