This is untrue. In New Zealand we locked down a reasonable amount for the information we have on the case. With the current lockdown, there was a single case with no known link to the border which had traveled around the country while infectious. Knowing just this and that every case in managed isolation (iirc) was is the Delta variant, we went into lockdown.
Also, '5 lockdown' is misrepresentive. We can see on this page
https://covid19.govt.nz/alert-levels-and-updates/history-of-...
that while some lockdowns were very restrictive, country wide, and long (2.5 months), most were short and regional (with other regions maybe going to lvl 2 alert)
It's a very weak benefit. I don't know about you but most of my time programming is spent thinking about the program, not writing it. In fact, this would only increase the time I need to think about how to write things (what was the symbol for reduce again?)
And easier to spot patterns in the source files. Whether someone finds that beneficial or not is subjective I guess, but I think it's useful to be able to immediately recognise what something like +/! is doing whenever you see it in source after using it once or twice.
