Absolutely if the demand and user base is there then it would be good for Orion to improve Touch Bar usability, especially some of the easier wins like additional buttons.
In many threads including this one the developers mention how limited their resources are so have to be selective about what to implement, so if it's between developing something that will benefit all users vs something that will benefit an ever-shrinking percentage then I would prioritise the former vs things like replicating Safari's complex custom tab switcher – I'm not aware of a single new Touch Bar feature announced in upcoming Sonoma, nor anything notable in Ventura or Monterey, so unfortunately not even Apple seem to be able to invest development resources into it anymore.
In the mean time regardless of whether the Orion team can add anything new there are great third-party tools available that allow adding a range extra functionality to the Touch Bar when using Orion!
