I believe the reason behind the removal of the above two services is because the development effort to modernize them going forward was greater than what they were worth.
CCP Falcon had this to say about the captain’s quarters:
Removal of the bounty system would take development time and provide little benefit. People who ignore it would continue to do so. People who use it will continue to do so to relatively little effect.
I’m not advocating for the removal or retention of the feature, but only trying to answer your curiosity as a courtesy.
