True, but when learning OSI in 90s - they were always refered to as 'layers' of the same protocol. Stacks where completely stand-alone applications connected which were not layers of the same protocol/system. I think that the simple way is to refer to them as stacks now, but if you were raised on LAYERS - refering to OSI as 'stacks' feels foreign. It appearsthat as we atomoze / containerize various teck, we now thing of them as 'stacks' rather than layers. It seems that 'layers' are now 'services' rather.
