>GNOME2->3

I assume MATE is still supported. Yes, it requires user action to change the DE, but end result may be worth it.

>init->systemd

OpenRC supported on Gentoo.

>alsa->pulse->pipewire

Pulseaudio is optional. Pipewire might be worthwhile to hear out.

>ifconfig->ip

ifconfig still works for me.

>NetworkManager->iwctl

No idea, never used any of those.
