JerBrains does something similar (after paying for a year I get perpetual license for the version released that year). I’m pretty happy and feel under control. I have been paying them for years now and in case they screw up I will stop my subscription and still can download and use old version. Sure I will be missing on some bug fixes but I have used the software for a year already, I can live with those annoyances. It’s not like the new version will be all bug free either.
