However, some stimming may become pleasure stimulating and begin to take on addictive qualities.
Unlikely. Most people who stim, if their stimming is not inhibited and their overall environment is stable, will not show the classic escalation pattern of an addictive behavior. The closest I can think of to addictive "stimming" is self-harm in people with mood disorders or borderline PD, and it's arguable whether self-harm due to those conditions actually counts as stimming.
