I understand your frustration when you say "As a keyboard user, the effort
of tabbing around the date-picker (especially with multiple years available)
was a big hassle."

Out of curiosity, did you encounter the same level of difficulty at
http://whatsock.com/tsg/Coding%20Arena/ARIA%20Date%20Pickers/ARIA%20Date%20Picker%20(Basic)/demo.htm
The keystrokes being:
Press the Left and Right arrow keys to navigate the row by week day.
Press the Home and End keys to jump to the beginning or end of the current
row.
Press the Up and Down arrow keys to navigate between weeks on the same week
day.
Press the PageDown and PageUp keys to navigate backwards or forwards by
month.
Press Alt+PageDown and Alt+PageUp to navigate backwards or forwards by year.
Press the Enter key to activate the selected date.
Press Escape to close the calendar without making a selection.

Back to the jQuery UI date picker, if the only way to overcome in-built
accessibility issues is to recommend that people just type the date in
manually, then it defeats the purpose of an accessible date picker.

Often the value of a date picker, is to make it easy to identify which dates
fall on a certain day of the week, which is valuable weeks, months, or years
down the road, such as when making travel plans for instance.

It's not a good accessibility solution to simply state that disabled people
should just figure it out on their own.
