Hmm. Looks like an oversight. File a bug?
Not an oversight.
Date.add and Date.roll are for adding units that are variable.
For example, how many days are in a month? Answer: depends on the month.
How many days in a year? Answer: depends on the year.
But days are NOT variable, there are exactly 24 hours in a day. So to
add a day, you just add a day with +=.
