P1902R1 introduced the feature test macro __cpp_lib_nothrow_convertible, but every other example in SD-6 of a feature test macro testing for the presence of a single type trait FOO is named __cpp_lib_FOO. This macro should be renamed __cpp_lib_is_nothrow_convertible.This naming convention should probably be documented in SD-6 as policy.

Status to Tentatively Ready and priority to 0 after seven positive votes on the reflector. A convincing argument was that currently no vendor had published a release with the previous feature macro.
