Exactly this. As much derided as the ST's OS is by Amiga fans, in actuality its fundamental architecture had more potential for future improvement than the Amiga's, though that never happened (in the mainstream, there's now FreeMiNT and friends). Why? Because it implemented syscalls through proper TRAPs, for one. While the actual implementation of the core OS wasn't multitasking or even have re-entrant syscalls, others came along and made it so (MiNT, etc) while retaining syscall compatibility. And the thing can be made to use memory protection, etc. even. The problem with the whole Amiga package is that it was brilliant for 1985, but extremely dated for the mid-90s and the reliance on the custom chips arch there just really couldn't evolve well.
