Sweeter indeed, amount of sugar im food is absolutely insane these days. I am from Russia, and food in Uk is like 3 times sweeter, there is added sugar on freaking Roasted Vegetables! Its bonkers!
There are plenty of bread recipes that require no sweetener, and it's definitely not needed for yeast to develop.
A lot of the packaged supermarket bread has additives to keep it fresher longer, one of which is sugar. Go either a little upmarket or to the baked-in-store section and you'll find some without it.
Bread has been staple food for millennia. For most of that time, sugar was rare, expensive or totally unavailable.
