The reason for this habit is that many years ago I got bitten by
trying to add a line in the last case.  The habit subsequently
adopted has proven very effective at eliminating such errors.

This is no different from insisting in using "Yoda conditions",

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.

In reality we all know that regardless of how many scary
stories someone might tell about dangers of accidental
assignment in place of comparison, it just does not happen.
There's no such issue.  People just don't make this mistake.

Your view is contradicted by objective reality.

The same applies to

This is the right thing to do.  It is the most readable and
elegant way to write a simple `if`.

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

And the dreaded "one day you will add a line and suffer" just
doesn't happen.  There's no such issue.  People just don't make
this mistake.

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