Replacing a system function is a quick and easy hammer but not great for maintenance. It's not clear that calls to Math.random() are now actually going to an npm, and if someone deletes that seedrandom line it's not clear that calls to Math.random() are now not actually going to an npm. For new/clean code it's better to just import a seeded random function for clarity.
