All I know is jdMorgan, the previous moderator of this forum who was second to none being an Apache guru pushed the optimizations so if the guru said it made a difference, and I know I've read those discussions a time or two and I'm not digging them up at the moment.
Whether others use that syntax or not doesn't impress me at all because people don't tend to study the code, or the manual in detail, and get the finer points which some do and others don't.
jsMorgan obviously had reasons and he was the guy that originally published a more optimal WordPress .htaccess section here which skipped images and such which was a massive improvement over the stock garbage WP and Joomla still publish.
However, if I had the time to really profile the code and verify the savings were as infinitesimally small as you claim, then I'd probably drop the code if the implementation overly complicated it with no realistic gain.
Anyway, optimization isn't the topic so let's get back to the thread topic.
