As I remember it, the timeline for removal of the feature was not brought up during the meeting. The minutes also don't record that.

The focus of the deprecation discussion was which of 01 and 001 would be deprecated, with the goal to align the C and C++ deprecations to ensure compatibility.

Hi all,

With respect to the deprecation of multi-digit octal literals using the plain 0 suffix, there is a culture (in WG 21) of expecting that deprecation leads to eventual removal. Was that clear in the discussion in April (https://github.com/sg22-c-cpp-standard-compatibility/sg-compatibility/blob/main/meetings/2026-04-24.md)?
