How long will the latest versions of Vray be compatible with Max 2019?

If I were to stay on 3ds Max version 2019 and not upgrade anymore, how many years will I get the latest versions of Vray for this version of Max? Thanks in advance.

VRay 3 for 3dsMax2012 died with release of 3.5 (Feb 2017)

So typically 5-6 years? Can anyone else confirm that this will be the case too moving forward?

Also worth keeping in mind that potential new features won’t work with older versions. Like the new ipr within the viewport doesn’t work in max2016.
