I'd be surprised if 'most' programs fill in the in-reply-to header then 
ignore it on incoming mail. If that's true then users of those programs 
will have a poor experience compared to proper threading (for example 
the thread will run in order the mails were received instead of who 
replied-to what...).

I've used mozilla / thunderbird for ages now. It gives in-reply-to 
headers precedence, but if the headers are missing it threads according 
to subject. eg. all spams without a subject are threaded together!
