Systems without updating mechanisms or unsupportive manufacturers shouldn't suffer too badly, as seen by the PS2. Blu-Ray's won't be expecting a non-existent firmware revision to be present and most of the incompatibilities happen when scenarios like Disc A from 2016 expects Player X from 2010 to have firmware 1.5 from 2015 installed, with it refusing to play when it's notices that the firmware level is still just 1.2 from 2012.
They wouldn't have that mandate on their disc for firmware 1.5 if it didn't exist for said hardware and wasn't possible to update the hardware to those specifications.
