CSSO itself doesn't use
source-mapdirectly (only as dev dependency for tests). Update should be in css-tree or/and csso-cli (so you need to fill an issue in that repos). Now they're using 6.x branch, because 0.7+ is using async API for SourceMapCustomer that's not suitable. Moreover, any performance boost is gained only in case when you input and output have source maps and huge enough – so that's not an issue in many cases.
