It's not the standards for vinyl playback that have changed, it's still the same RIAA curves, same rpm standards and the exact same electromechanical interface. Tonearm design, plinths, formulations etc. are variations not change of governing principles as is happening for streaming. 44/16 CD standard was set from the start for CD medium, it hasn't changed. Upsampling, converting, downsampling etc. are tone controls Redbook CD was and is forever 44/16 and PCM, datafiles and retrieval principles AFAIK are also fixed. Streaming has some protocols but no standards at this point even the basics like the players and network protocols are constantly changing. This is all fine and it's a great tool for access my point is that as it stands sonically even at it's best it's good midfi at best and still far from high end.
