Not possible
However as you are in the EU, Facebook have to add 3rd party support to whatsapp. So that people on whatsapp can still message users who are not on whatsapp. Later in the future, group support will be added.
No time frame of when it goes live.

Only use for status is to say you're on Signal.
What's stopping someone from enabling debug mode, downloading adb tools and running pm uninstall --user0 then the package name? Surely with the app removed, the app can't brick your phone. Or running a custom rom like lineage or graphine os?
Especially 3D objects
DON'T HOLD BACK!
Iso date format. Anything to do with photos is best to have in this format at the start of the filename.
Computer, load programe Big Lebowski with the Jesus as bowling opponent.
Says signal sucks without actually trying it. Just create a group chat put a link in, job done
Maybe same text just laforge format. Fediverce is star trek.
I think it's worth it.
Just simply send a link along with that's generally better and that lots of people are moving over. Watomatic could be looked into as a way to automatically remind people you are on signal when they go to Facebook you. It would then prompt then to install signal.
I take the attitude if they want to contact me either, phone, email or text.
There are none. As its Facebook.
You are better of inviting them to Signal. If they know how to use WhatsApp, then they know how to use Signal. It's designed to be as easy as possible, while secure and private.
Networking effect
Mastodon required people to join a server which made out to people who are used to signing up to a single website for the past 20 years or such, seam too complex.
You also end up in a situation where social media managers have to reach engagement and impression targets and don't think which is best platform that will not be taken over Elon musk or Mark Zuckerberg style, but which will reach engagement targets the quickest.
