But the problem is that it does interfere with things in subtle ways.

Here's a simple scenario - you want to draw in a line with the intention of using it as the cutting object in boolean difference.

But boolean difference doesn't just work on a single selection, it needs 2 separate selections, one for the base objects and then a second selection step where you give it the cutting objects.

If a newly drawn line was selected automatically you now need to do an extra step to deselect it before you can run boolean difference because it needs to be selected as a cutting object not as a base object.

It's just not the case that it would universally be helpful to alter the selection like that.
