Update of PROJ requirement is proposed with PR:
The question is, wouldn’t it be better to bump requirement to version 9, and possibly to a point release up till 9.2–9.4? The version 8 was very much a spring board to the new API–it was quickly replaced with 9–and is not the default version on any of the (important) platforms. Such a bump would not currently make any difference in GRASS code, but may in the future… Thoughts anyone?
