It's not very clear from the article, but the proposed measures are public and the EC is running a public consultation until 13 May:

https://digital-markets-act.ec.europa.eu/dma100220-consultat...

The consultation is mostly addressed to developers. And there's a lot of interesting stuff in there:

- Always-on custom hot words (via DSP)

- Access to App search

- Interoperability with Magic Cue

- Access to contextual/ambient data (e.g. to build Magic Cue alternatives)

- Ability to run App Functions exposed by other apps (these are currently system privileged, unlike standard Android intents)

- Screen automation

- APIs for better integration with Google cloud services

- On-device models

- Background execution

This stuff can be very exciting for a lot of apps, people working on Android apps should reply to the public consultation even just to say that they agree with the measures.
