That is true, now, under RDA, but a lot of those Wilson, Pete. $t Works. $k Selections. $f 2019 style headings were created in AACR2. They were then programmatically recoded as RDA. For Wilson, Pete. $t Works. $k Selections. $f 2019 to make sense as an expression heading there would have to be only 1 selection of Pete’s works, but multiple expressions of that 1 selection such that you would need the date to distinguish them.
The first form (date in $f) is an AAP for an Expression. The second form (parenthetical date in $k) is an AAP for a Work.
I got curious about something and looked through the NAF a little at name-title headings that include “Selections.”
I was surprised at how many recently created authorities use this form:
Wilson, Pete. $t Works. $k Selections. $f 2019
Wilson, Pete. $t Works. $k Selections (2019)
I thought the question of whether to qualify with an $f subfield or just enclose the qualifier in parentheses in the $k had been fully decided, or as fully as such questions can ever be decided. Is that correct, or is there still a live difference of opinion among the “experts?”
