You are correct about always using braces; this I want to see strictly

Unfortunately those detached indented braces make this extremely hard for
me to read.  This looks similar to the style used in kwin?

In my experience even if the brace is "invisible" after an if the presence
of a control statement plus indentation (and combined with the braces
always used rule) are more than sufficient as replacement cues.  In effect
what I like about placing the brace at the end is that the control
statement and brace form a single "statment"; i.e. my eye only has to jump
one line to read the next chunk of control flow instead of having to jump
two with the second containing a good bit of whitespace.  That same
whitespace causes my eye to sometimes miss the initial statement of the
next code, forcing a retrack and often pushing something else out of
working memory in the process--this is the main reason I tend to mess up
the control flow in twin commits and have to go back to fix it.

If I were to excercise the power of the BDFL on this project and override
the braces to the way I want to see them would this be a major problem?
