I did some searching and Signal indeed stated they won't do it. It seems
the DMA was only meant for Meta (WhatsApp and Facebook Messenger). At
least that's how it seems to me. Signal has a problem with it since Meta
won't let Signal have a look at their encryption while Signal's is open
source.

I think this is a shame. I am on signal and not on whatsapp. But I know
the vast majority won't shift just because of a small minority. And that
is their choice. If they interoperate then there won't be so much
pressure on people to join or stay on whatsapp. As whatsapp users
already have my telephone number in their contacts, and whatsapp has
access to that, it wouldn't matter much. Or they could use an arbitrary
identifier.

Whatsapp uses the Signal protocol. How did they make open source into
closed source? "The Signal Protocol is licensed under the GNU Affero
