If implemntations have been around for a while but it only happened now, then it's 99% chance that's it's Apple backpedalling and trying to weasel their way around DMA.
5.4.8. Implementation timing
(245) Apple should provide effective interoperability with the P2P Wi-Fi connection
feature by implementing the measures for Wi-Fi Aware 4.0 in the next major iOS
release, i.e. iOS 19, at the latest, and for Wi-Fi Aware 5.0 in the next iOS release at
the latest nine months following the introduction of the Wi-Fi Aware 5.0
specification.
These rulings only affect third-party apps, not AirDrop. Apple is not required to stop using AWDL for system apps, and is also not required to allow third-party implementations of the AirDrop protocol. They are however required to implement a mechanism allowing competing solutions to automatically trigger a prompt to install their own iOS apps, but the deadline for that isn't until next year and they have not yet shipped it.
They got smoked in court, see ruling at https://ec.europa.eu/competition/digital_markets_act/cases/2...
