Note that this problem is not unique to the for() statement. An
assignment statement allows you to arrange three unrelated expressions
together like

A = B + C;

"Doctor, it hurts when I hit my head with a hammer!"
"Then stop doing that."

The key to using the for() statement is to make sure the three
expressions are related appropriately. Many different powerful and
useful ways of using a for() statement have been shown in this thread
that are not equivalent to for(int i=start; i<end; i += increment).
Individually, those uses aren't particularly common, but collectively
I've needed each of those uses often enough to be grateful that C has
such a flexible construct to do it with.
