This is honestly to be expected. However, while encoding times have heavily increased and may eventually be a barrier for further optimizations, I don't expect that to occur until the drawbacks of said encoding times outweigh the benefits. In this case, massive savings in bandwidth (around 50% for hevc/vp9. Maybe a bit more for AV1). That would definitely be the biggest cost for a company like Netflix and other providers that deliver large amounts of data over a small set of files.
Eventually I think AV1 will win out over HEVC and VP9. In the case of HEVC, the patent mess has hindered adoption. In the case of VP9, the somewhat poor spec has done the same. Since AV1 seems to be a good attempt at fixing both along with the mass of companies that back it, there is a good chance that things will move quickly to just this one format. Google, Mozilla and Microsoft can simply ship updated browsers and add support for the format within a short period of time. Youtube will then slowly drop VP9 just like it dropped VP8 and h.264 (no 4k encodes in this case anymore).
