I'd say extremely unlikely — it wouldn't make sense both technically (stable, mature, small, razor-focused libraries that are already open source) and business-wise.
As far as I know as someone who worked here for 7+ years (take this as personal opinion), Mapbox wants to keep investing heavily in open source and open data sustainably and indefinitely, and this GL JS change is an unevitable prerequisite for that. This may not be easily apparent at this moment but it will be soon.
