Not really. Linus thought he was building a toy kernel but as soon as it was released it became a real OS as people got it working on their systems, got all GNU programs running, etc. The X windowing system was ported in less than a year so it was a full fledged OS immediately. As for minux, at the time Linux was released microkernels weren’t considered practical outside of research OSs until the mid-to-late 90s and even today Mac OS is the only widely used micro kernel OS. This is a big topic of Linus debate with Tannenbaum. I don’t recall the exact reasons but iirc microkernels we’re/are slower than a monolith and at a time when computing power was much lower they didn’t make sense for workstations.
