Here's an answer with implied pointers to sources for similar answers:

git annotate shows that a relevant line in cmds.c was changed by
commit 81f0e05 on 2018-11-17, with the log entry:

  * src/cmds.c (Fself_insert_command): Get last-command-event via (new) arg.

The diff for that commit shows that it also adds an entry to etc/NEWS
under "Lisp Changes in Emacs 27.1".

To confirm from a different perspective, the Emacs 27.1 I'm using from
Arch has the two-argument form.
