Note: Even if Photoshop/Lightroom did embed these in the RAW files, the problem of actually loading the embedded information would still be there for Affinity. So the point here isn't the file separation; the point is Affinity doesn't understand the postprocessing Photoshop has already done on the photo.
The feature has been requested a lot; see for example https://forum.affinity.serif.com/index.php?/topic/113871-use... and https://forum.affinity.serif.com/index.php?/topic/45772-can-...
You're very confused, catalog vs. XMP (or classic vs. modern) is entirely irrelevant. Heck, the catalog is objectively worse. You're switching software and want to still be able to use the post-processing you've applied to your photos. Which Affinity can't do. It's irrelevant where or how that information was stored.
Seriously? You don't feel it's ridiculous to say this when just above I posted links to people begging for this feature on the forums since at least 2017?
> You can hate on one application or another
I'm not hating on it - if I hated Affinity I wouldn't even be wasting my time to point it out. I love Affinity and want it to succeed, hence all this.
First, thanks for acknowledging that it's not "just me". That kind of nonsensical hyperbole doesn't help the discussion.
Second: You have no idea if it's a minority of the market that actually wants this. The majority of users obviously use Adobe, that should tell you more than how many people are voicing their opinions in a forum. Not every user goes out of their way to re-request a feature that's already been requested years ago.
> doesn't mean it's a deal-breaker for other users.
Nobody said it's a deal breaker for "other users".
> Clearly the company behind the product agrees, otherwise they would've implemented it.
Because there's no other possible reason we could fathom as to why they wouldn't have implemented this already, right?
Again: nobody said it was "universal", but again: it's not about me, either. It's ridiculous that you're still insisting it's just me when you literally see other people complaining about it. You clearly aren't interested in having a reasonable conversation so there's no point in continuing to engage.
