This was also true of H.265 in its early days before there was widespread support. I once had to wrangle a few workstations to act as a renderfarm overnight in order to transcode a couple hours of footage by the next morning having not been aware that we were dealing with H.265 until the day before it had to be done.

But also yes, as others are pointing out, this is a problem rapidly being addressed and is not atypical for new media formats.
