Keep in mind that Apple's choices to postpone features for the EU as a punishment for the DMA aren't always related to the actual contents of the law, and reek more of trying to find any excuse to block a flagship feature if compliance would take any effort whatsoever.

Take for instance iPhone Mirroring; on paper it's not a technology affected by the DMA at all (in fact, I can literally use my Android phone and adb/scrcpy to cast my phone screen and audio to desktop right now, screen casting isn't some super sacred tech), but Apple has claimed it does for the DMA. Their argument for claiming this is pretty floppy (the way I understand this is that Apple wants to use their own proprietary protocol and doesn't want to provide the protocol specs/cross-platform ways to use that protocol, which is what the DMA asks of them since they're that big of a player - Apple publicly says it'd compromise security, but it should be noted that Apple trots out security as the reason for almost every consumer hostile thing they've ever done in recent memory), but making a big show out of how the EU is evil helps them more, rather than the reality just being wilful noncompliance.

Apple has been bad faith on the DMAs contents from day one, and basically all of their complaints come from that bad faith attempt to comply with it. Junk fees like the CTF/CTC, requiring one million dollars in the bank for app stores and still trying to gatekeep non-app store apps, withholding random features because making them compliant takes a bit of effort: they are all examples of Apple thinking that if they're just obstinate enough about non-compliance with the DMA, that the CJEU or the EC will make the law magically go away by giving them an inch. That may work in the US, but so far it's not exactly been doing wonders in the EU, which tends to just get more pissed off.
