https://raw.githubusercontent.com/Homebrew/homebrew-core/$GDAL_COMMIT_SHA/Formula/g/gdal.rb
curl -X GET https://raw.githubusercontent.com/Homebrew/homebrew-core/$GDAL_COMMIT_SHA/Formula/g/gdal.rb > Formula/gdal.rb 

What's wrong with brew extract --version=3.7.2 gdal grumbling-tom/tom-test-tap

In running an extact, the formula loses its bottles (pre-built binaries).

One main advantage of using brew for GDAL is to avoid needing to compile on a given machine. Given that, we are motivated to find an alternative solution that avails of upstream bottles.

Is this a good idea?

Probably not, for reasons that Future Tom can elaborate on.
