I can confirm.  So sr0 is visible.  The same happens for me on an
internal and an external USB DVD drive when I insert a video DVD, but
I can play it with VLC and once I open the drive /dev/sr0 in VLC it
gets auto-mounted in Nautilus.  Note that I have gvfs in my packages
field, if that makes a difference.

On Arch the DVD gets mounted by Nautilus immediately on insert.

I have no idea why that happens though.
