I would guess to make them consistent with kbd, insert-kdb-macro,
edit-kbd-macro, and view-lossage.

TAB (aka C-i) and C-h are ASCII characters and thus are categorized as
keyboard events. <tab> is a function key, and <S-tab> is a modified
function key.

The Keyboard Events node of the Emacs Lisp manual says "The 2**25 bit in
the character code indicates an ASCII control character typed with the
shift key held down." So if you want a Shift-TAB, try (kbd "S-TAB"),
[(shift ?\t)], or [?\S-\C-i].
