> I sometimes find the format string more readable than lots of small strings fragments +'d together. But I don't feel strongly enough about to to break local convention.

Not everybody memorizes this Python-style format string, and lld doesn't have a lot of code that needs formatting strings (so even if there's something better, investing in it isn't worth the cost), so we generally avoid using that in lld.
