Autorepeat - form_date / to_date

I had a look at

set_auto_repeat_period()

in

frappe-bench/apps/frappe/frappe/automation/doctype/auto_repeat/auto_repeat.py

There I found that from_date and to_date only get set when the period is in

{'Monthly': 1, 'Quarterly': 3, 'Half-yearly': 6, 'Yearly': 12}

Is there a good reason for not setting from_date and to_date when period is “Daily” or “Weekly”?
