OpenBSD does support SMP since 2004, FreeBSD even earlier.
You seem to confuse SMP with Intel's "HyperThreading", which is disabled on OpenBSD due to security concerns (SPECTRE et al.) and which makes sense to default to in an OS that takes security seriously.
SMP and HyperThreading are completely different things.
