It is not like we do not want it, I think. If you read https://git.github.io/SoC-2025-Microprojects/ (the first entry) carefully, it does not say "find anything that -Wsign-compare warns about and squelch the warning by using widest type common among the quantities involved in the expression the compiler warns about" at all. Most specifically, it does *not* tell you to achieve it "by using widest type". You would squelch the warning using the most appropriate type, which may not be the widest one. In the case we discussed in this thread, it was line number whose type was the platform natural integer, but mixed up with other size_t things that caused the compiler warning. Blindly using size_t to squelch it may not be what we want, but that does not mean we do not want to squelch it by doing something else (like, by not bringing "size_t" quantity into the picture).
