To answer the OP ... Some of the features may be "niche" and of limited use now, but they lay the groundwork for expanding on those features further into development.
Many on this forum have been here since the kickstarter, and have seen this game develop almost from nothing. The general pattern Frontier had shown is:
Put a feature in with limited features and use.
Bug fix and get that feature working smoothly
Expand on that feature with more features and use and variety
Bug fix on the feature and get it working even more smoothly
Expand again and bug fix ... unless feature is considered done or complete or complete until other features are at a sufficient stage.
YOU might think X is limited now, but you and I are not privvy to Frontier's development meetings and what their roadmap / list is.
Have faith, and trust that Frontier know what they are doing
