I believe Reflection is being taken very seriously and will be included in standard 26.
The Fine Article, meaning what the HN submission links to.
I've always been mystified by that expansion. "The featured article" seems to me to make much more sense.
Originally, it stands for "The Fucking Article", as in "RTFA" (= "Read the fucking article"). The expansion "The Fine Article" is a humorous reference to the former.
Note that over the years "TFA" has lost its profane meaning and is generally used in a neutral way.
Planned to be included, it remains open if it will indeed.
