Shouldn't be any other way. Modularity is such a nice idea. Much nicer than spinning up something that takes 600 MB of RAM in components not necessary to completing the task at hand.

Maybe if electron's dependencies could be compiled down to the minimum functionality needed by a given application this could work.

As far as Alacritty is concerned, modularity can easily come with a cost.

once you add in e.g. tmux for multiplexing and scrollback, then you are bottlenecked at tmux's speeds, as opposed to the terminal emulator's speeds (not like it really matters, but its an interesting effect)

That will be interesting for the tmux (or do we go all the way to nurses??) developers, because tmux has probably always been way faster than any terminal emulator it has been running in.

Where will the bottleneck be?

I ain't too sure, but

I wonder if Chrome providing a headless mode could somehow improve things.

Doesn't headless mode just mean rendering to a bitmap instead of a window?

No, but it's usually used to take screenshots and stuff like that.

It means rendering without the UI from what I understand.
