Repeating the last character is the most convenient way to repeat the command,
indeed.  No other key combination would be equally easy to type.  For example,
when there is a need to navigate next-error locations with 'M-g n M-g n ...'
changing the modifier key in 'M-g n C-=' won't do it better than just
'M-g n n n ...'

But since typing a self-inserting key is ambiguous, and sometimes requires
typing another key to break the key sequence to insert the character,
this means that such feature should be optional.

In this case it's easy to implement it as a minor mode that uses hooks,
e.g. last-char-repeatable-mode added to repeat.el.

This could be like delete-selection-mode that by default
puts a special property on symbols of affected commands.
