Installing Crimson manually over Byzantium

It’s fantastic news that Crimson is released, my great appreciation and thanks to the whole team!
I am also looking to install Crimson manually after the GUI tool identified several foreign packages. I did a --dry-run full upgrade just to be safe and look over the output and found this:

WARNING: The following essential packages will be removed.
This should NOT be done unless you know exactly what you are doing!
  librem5-gnome librem5-gnome-phone (due to librem5-gnome)
  chatty (due to librem5-gnome-phone)

Now I see further down the output that librem5-gnome-base will be installed, but I don’t see the same for Chatty.

Should I hold off upgrading or am I just being too cautious?

For some more context, I installed many of the Byzantium backports that were created and packaged by galilley in 2024. They’ve worked spectacularly for the past two years (for example being able to use the newer version 0.39.0 of Phosh, for all this time) but I always suspected I might run into issues once the official OS upgrade came along.
Along those lines I also noticed seven packages being kept back which I suspect stems from having utilized the backports:

The following packages have been kept back:
  gnome-control-center gnome-settings-daemon gnome-settings-daemon-common
  libinput-bin libinput10 libwacom-bin libwacom-common
