Don't be silly, of course they are different.  There is nothing
artificial about surrounding controlled statements with braces.
And writing braceless single-line if()s in cases where there
is only a single controlled statement is something I was already
doing - I didn't adopt it as a reaction to something that
happened with multi-line if()s.

Your view is contradicted by objective reality.

I think you need to learn the difference between a statement
of opinion and a statement of fact.

Making a false statement twice doesn't make it true.
