(I’m also a fan of rebasing; but I also like to land commits that perform a logical and separable chunk of work, because I like history to have decent narrative flow.)

Doesn’t need to be a “traditional” container. Modulo noisy-neighbour issues, wasm sandboxing could potentially offer an order of magnitude better density (depending on what you’re running; this might be more suited to specific tasks than providing a substrate for a general-purpose conpute service).

That’s not correct, but it shouldn’t preclude you from applying defence in depth.

I don’t know where you get “listing” = “logging”. It’s a term (apparently archaic, today I learnt I’m old) for the text of a program.
