Consider the term orphan (or orphaned, if an adjective would better suit). According to Merriam-Webster, one of its meanings is
one deprived of some protection or advantage: orphans of the storm
The term has some use along these lines in other fields. The term orphan works is used to describe
An orphan work is a copyright protected work for which rightsholders are positively indeterminate or uncontactable. [Wikipedia]
In effect, these are works are effectively abandoned, even though they are arguably still owned.
The term orphan disease is used in medicine to describe diseases whose drug treatment would be neglected because of the rarity of the condition and the unprofitability to drug companies to develop or manufacture such drugs. There are governmental programs to foster the manufacture of such drugs, called orphan drugs.
It sounds like your features will be orphaned. They will not be cared for or protected by you, but they continue to have an existence. And, like an absent parent, you may decide to go back and nourish them someday.
