Skill scrubber removes skill given to a duplicant by their Traits

This is probably somewhere on the borderline of a bug or unintended/unthought behaviour. When I have a duplicant that came with a learned Skill from getgo in their Trait (Skilled: Mechatronic Engineer), it does not make sense for this skill to be removed/scrubbed when they go through the skillscrubber. I might level up this dupe and give them some skills, and later on decide to change them. I don't think the skill they had from the printing pod and still have it in their Traits list should be removed as well when they get skillscrubbed. Thoughts?
