Wezterm does have tabs, and their related keyboard shortcuts are configurable.
See https://wezfurlong.org/wezterm/config/lua/keyassignment/Spaw... for a starting point in the config.

For example, I can select a tab in Ghostty, pull it out into its own window, and then stick it into another window. This doesn't work in WezTerm, nor can you drag them around to rearrange them (keyboard shortcuts allow this however).
Maybe it does not matter, the difference in functionality should count. Just highlighting that this messaging might not be understandable for linux users. I guess you are talking about some macOS thingie that's irrelevant to us.
AppKit/SwiftUI on macOS and GTK/Qt on Linux.
