I wonder if someone can clarify if UDF version 2.5 or higher really is required for creating and burning Blu-ray video to VBD-discs (blu-ray video discs)

The latest version of Fedora, i.e. version 36, has udftools version 2.3 and my laptop with Fedora 32 has udftools version 2.1. Both have been and continue to work to create blu-ray discs by the CinGG method.

Yeah, that corresponds to the state on Leap/Tumbleweed.

I've also inspected a couple of other discs with udfinfo, discs that works on my Samsung Blu-ray player:

This disc created with udftools 1.3 from Leap's main repo
label=LinuxUDF
lvid=LinuxUDF
vid=LinuxUDF
vsid=LinuxUDF
fsid=LinuxUDF
fullvsid=63890d51c6cae8fcLinuxUDF
owner=Linux mkudffs 1.3
organization=Linux udftools 1.3
contact=https://github.com/pali/udftools/
appid=*Linux mkudffs
impid=*Linux UDFFS
udfrev=2.01
udfwriterev=2.01

and this one created a year ago - I expect with tsMuxer, first as an .iso image file (?) while the disc show udf version 2.5 (?)
udfrev=2.50
udfwriterev=2.50
