The maintainers would prefer to "do one thing well" and let other programs handle this sort of feature.

You can use tabbed[1] or a multiplexer like tmux, or you can use a different terminal emulator like kitty[2].

For example, instead of launching `alacritty`, you would launch `tabbed -c alacritty --embed`.
