Will there be support for Camera RAW/LR/PS for the Canon 28-70/f2 soon? If not how would I make a custom one or has someone already invented that wheel?

RF lenses have profiles made by Canon, which are embedded in the raw image. That is why Adobe does not need to make their own profiles.

So when I want to apply lens corrections in Lr is there something I need to do to apply the canon profile?

No, the embedded profiles are automatically applied. You could not even turn that off if you wanted to. There should be a note at the bottom of the Lens Corrections tab that says that the profile is applied. The only exception to this seems to be the RF 24-105 lens. Adobe did make a profile for that lens, so perhaps Canon did not.

I've seen this thread referenced elsewhere and it's causing confusion: Right now (2019-07-23) Adobe does NOT support the embedded RF profiles:

Embedded profiles are always supported, but apparently RF-lenses do not have embedded profiles. That means Adobe profiles should be added in some future release, but as we all know Adobe does not comment on future releases.

Canon RF lenses do have embedded profiles. That's how the R series bodies know how to do the in-camera corrections. See section 13.2 in https://downloads.canon.com/nw/camera/misc-pages/eos-r/pdf/canon_eos_r_white_paper.pdf

What I think you mean to say is that:
  • The profile isn't added to the metadata.
or
  • The profile is added to the metadata, but Adobe isn't using it yet.
But in the white paper Canon mentions that their DPP software can do the corrections as well, so that implies that there is at least some metadata present.

Profiles are embedded (or not) in the metadata of the images. The camera does that, based on its recognition of the lens. That is why things can go wrong and so you can get the wrong embedded profile: my Sony A7R III camera embeds a profile for a Sony 24-70mm lens when in reality I used a Canon 24-70mm lens with a Metabones adapter. Fortunately this profile only corrects chromatic aberration, not distortion, so it doesn't do any visible harm.

As far as I understand it, Canon R cameras do not embed the profile in the images. That does not mean they can't use a profile to correct their JPEG output, and it doesn't mean that Canon DPP cannot apply a profile by reading the lens data in the metadata. Both is perfectly possible without embedding the profile itself in the image. Your link could be interesting in this respect, but it leads to a 'Referral Denied' error.

If that is the case, why would there be EOS R and RF 24-105 F4?  I want to get EOS R and RF 28-70 F2 supported too.
