This note didn't have any references (which made sphinx complain), so I added a one to the day-of-month entry in the table. For reference, this was added in#117107

A possible negative is that footnotes are numbered sequentially throughout the whole file instead of restarting with 1 (because of the explicit number labels starting with 1). This, for instance, becomes file footnote 7 rather that table note 1.

date2 = date1 + timedelta | date2 will be timedelta.days days after date1. [7]

in the preview. On the other hand, The links to notes and backlinks from note to table line are nice, especially when multiple, as in

[1] (1,2,3,4) This is exact but may overflow.

where 1,2,3,4 link to the 4 items with this property. This is not such a big deal on my 4K monitor, but I imagine would be very helpful with phones, and I know there are coredevs and I presume other users that use phones. Overall, I think the change is positive.
