I'd make the change.  If someone wants the current behavior, we could add
a "special element" like 'line-number-display-start' such that

:align-to 0

would behave like

:align-to (+ line-number-display-start (line-number-display-width t))

for LTR text.  But I never use :align-to so I'm not very qualified to
comment on this.
