As discussed with @Gcenx this shouldn't be an issue, as the current minimum support version of 10.8 does not work anyways at the moment with only 10.10+ being useable and even then virtually no-one using wine on versions < 10.12 (and also being unsupported by the prebuilt binaries).
The Winehq macOS packages (installed via brew cask) require macOS Catalina (10.15.4) as of wine-stable-9.0.
The lowest version of macOS we should really care to support going forward should be macOS High Sierra as Xcode9.4.1 was the last version of officially support 32Bit, that's ignoring Xcode10 Command Line Tools `macOS_SDK_headers_for_macOS_10.14.pkg`
