Yes, we can make the proposed date display formatter use the selected
locale, overriding the browser locale.

That's unfortunate.  That doesn't negatively impact user experience in
other ways?

Well, that's the rub.  The format for native date / time inputs is dictated
by the browser, based on the browser locale.  If overriding input formats
is required, that essentially puts bug #1840782 to bed.

We still have the option of using the proposed date formatter for display
strings, but date / time inputs would require ng-bootstrap.  I'm not sure
if we'd still require MomentJS for date parsing, I need to review the code
for #1834662.

Thanks for the feedback, Jeff.
