Certain low-memory machines may also want it

This is a part of the misconceptions about it.

It doesn’t meaningfully help with that unless much harder constraints are applied in development where it would become relevant at run-time. It can be relevant for low-storage machines however. That’s what binary size is primarily about after all. And low-storage and low-memory may go hand in hand at times as device properties.

I’m not sure who’s recommending it
