I would argue that changing the default C mode to c23 in the year that comes out (or even a year later) is too aggressive and early. Existing sources are often compiled with defaults, and hence would change semantics, which seems unattractive. New code can instead easily use -std=c23 for a time. E.g. c99/gnu99 (a largish deviation from gnu90) was never default and gnu11 was made default only in 2014. Ciao, Michael.
