SG16 discussed this issue during its 2022-12-14 telecon. The following polls were taken:

• Poll 0.1: Forward D2675R1
  "format's width estimation is too approximate and not forward compatible",
  with improved presentation, to LEWG as the recommended resolution of LWG3780
  and NB comment FR-007-012.
  • Attendees: 6

    SF	F	N	A	SA
    3	3	0	0	0

  • Unanimous consent.
• Poll 0.2: Recommend that D2675R1 be applied to the C++23 working paper.
  • Attendees: 6

    SF	F	N	A	SA
    2	4	0	0	0

  • Unanimous consent.

P2675R1 reflects the presentation improvements requested in the first poll.

@brycelelbach, this is now ready for LEWG. I'm removing the SG16 and LWG labels.

@brycelelbach, I added the C++23 label since this paper is recommended as the resolution of NB comment FR-007-012.
