It's worth noting that libsass's source map support is still ironing out bugs (i.e. https://github.com/sass/libsass/pull/1463 https://github.com/sass/libsass/pull/1463), though it seems that the compilation itself is relatively solid. My team finds that the time saved in compilation for a Flask app is worth source maps sometimes not working. Your mileage may vary, though.
