[PROJ] EPSG release once more busted

Thank you  for your checks.
What I wanted to share is the example of the modifications made by EPSG that led to corruption of the transformation data.
This raises questions about EPSG's validation process.

I've just verified that the 12.059a update has reverted them back to using EPSG:4258 ETRS89.

can also be checked at:
