I believe the question at hand for those who believe there's more to be done is; what do you want in a DAW that hasn't been done already? That applies to any DAW, not just Reason.
There are countless other ways of composing, especially for people who like to sample their own works and mess around with glitch style effects that could be facilitated by the DAW.
After composing I sometimes bounce everything down to audio and treat the recordings as samples to mess around with. A DAW could facilitate this by providing a "composite" sample that is treated as if it was just a sample, but after I'd finished with all my mangling, I could go back into my original project the recording was made from and adjust the mix, or even better, be given a channel strip to control static channel strip settings for the sample so that I would be able to modify EQ, effects, etc.
For articulations you could have some algorithmic articulation assistant for orchestral instruments that would take your patterns, play around with your instrument (sampling necessary articulations, or even articulations between a set of selected instruments) and then transform it into a more lifelike performance for that particular instrument. This could be accompanied by additional articulation controls to better instruct the algorithm. Alternatively, just some improved support for manual composition with articulations in mind.
A built in database of phrases from your projects based around a chord or chord sequence could be provided to help facilitate composers who tend to build lots of loops that could probably be exchanged between unfinished songs. This may even be a common need and could be facilitated by library "inspiration / progression" sequences that contain a simple piano or guitar backing to form the foundation (or chord format) for your sequences.
For browsing patches, a DAW like Reason could facilitate the exploration of one's sounds with suggestions of patches, folders or refills.
Some of these are all things you can sort of do yourself manually to a certain extent. If you had some developers working directly with forward thinking engineers and composers, by just building tools around their workflow and needs you could probably come up with a variety of different angles for a DAW.
