FWIW, I am also about +0.5 on allowing trailing comma. Note that in a

allows a trailing comma after the list of enumeration constants. The
Committee decided to adopt this feature as an innocuous extension that
mirrors the trailing commas allowed in initializers.

Similarly, I find allowing trailing comma in keyword only arguments
lists to be an innocuous extension that mirrors the trailing commas
allowed in the positional arguments lists.

arranged lists, one per line, primarily, with ) on the last line by
