Proposed resolution (approved by CWG 2024-08-16):

Change in 15.7 [cpp.line] paragraph 2 as follows:

The line number of the current source line is the line number of the current physical source line, i.e. it is one greater than the number of new-line characters read or introduced in translation phase 1 (5.2 [lex.phases]) while processing the source file to the current token.

Given the existing implementation divergence, it should be clarified that __LINE__ counts physical source lines, not logical ones.
