Nice change.  Another variant is to add special symbols to
the existing customization, e.g.:

  '(5 ((shift) . 1) ((control) . text-scale) ((meta) . nil))

or even support text-scale step number if needed:

  '(5 ((shift) . 1) ((control) . (text-scale . 1)) ((meta) . nil))

This is similar to what I proposed with

  '((shift) . (hscroll . 1))

to scroll horizontally like Shift-wheel does in web browsers:
