CR3, convert to DNG! ... Currently dt is not fully importing some
critical EXIF data from DNG files. I have asked in redmine that this be
looked at.

Before you gave money to Canon, you could have checked the status of exiv2

Here's what you should do:

For time being you can convert your CR3 to DNG with no loss of image
information and metadata.
Remember - YOU supported canon with your purchase, you should expect THEM
to help open source devs with CR3 support, not other way around.

Will the forthcoming release of dt support Canon cr3 format?
I'm interested in this as well, having recently purchased a Canon EOS R
camera. There was some discussion in August, but the outcome back then
seemed to be that exiv2 (which Darktable uses) developers are too
uncertain of the possible legal issues and Canon is unwilling to give
any assurance that decoding the format is allowed. There was also some
talk on the relevant git issues about having to figure out how to
actually decode it without an official spec.
However, libraw has apparently had CR3 decoding support since November
2019. There's a fork of RawTherapee[1] with CR3 support (using libraw)
in a build from March, and it worked out of the box on my Debian
unstable system. So it seems that the format has been sufficiently
figured out and, at least so far, Canon has yet to raise a legal ruckus
about it.
So where does Darktable stand with this issue? If exiv2 is too mired in
their legal uncertainty, would using libraw either in addition or
instead of it be an option? I would prefer to stick with Darktable
since it's unlikely the XMP data can be transferred to a different
program at the drop of a hat.
