Yes, you’re right. But it doesn’t take too long 
I was thinking more of the added frustration. It’s an opportunity for accidents. Making a change, getting interrupted, and then thinking that the cell had been re-run. That the intent to re-run had been fulfilled, when it hadn’t been.
On occasion, I’ve spent hours or days trying to track down a problem that never was. It’s an occupational hazard that I like to reduce, when I can.

Rerunning cells out of order can lead to pain, that’s for sure. I must admit that it is rarely a problem for me. When I work in a notebook, I tend execute cells from top to bottom anyway in one fell swoop/button click (the effect is similar to running a Python script from the command line). Also, when I work interactively in an IDE (running things in the REPL), I also have to reload updated functions as well (assuming no auto reload has been set up), so in that sense there is still a pain there that is no different than using a notebook. Lots of work flows with different trade-offs I guess.
