Why no "standard" features like fn lock a new laptop

Got a swift air 16(SFA16-61M) recently thats overall is pretty good for my needs at the moment. Sure i can change the setting in the bios for what the fn key does but no quick change lock between media/f(nr) keys while running. No support yet for stopping charging while plugged in at 80-90% in the lack lustre acer care either but maybee it dosnt matter that much for longevity or?

Its pretty common features even on there other laptops and common among other brands to but eh whatever guess i can live with it.
