Why is there currently no bitcoin package in Debian? Why is the bitcoin package currently not in Debian? And how to help get it back in there?

It'd make it a lot easier for more people to run a full node with this.

If you drill into the details you find security bugs such as CVE-2019-15947 


  In Bitcoin Core 0.18.0, bitcoin-qt stores wallet.dat data unencrypted in memory. Upon a crash, it may dump a core file. If a user were to mishandle a core file, an attacker can reconstruct the user's wallet.dat file, including their private keys, via a grep "6231 0500" command.


I guess time needs to be spent resolving all the issues identified with the package.
