std.heap.SmpAllocator asserts !builtin.single_threaded #25992
Description
Is there a good reason that SmpAllocator asserts not single threaded other than a different implementation might be more efficient in a single threaded situation?
I tried deleting the comptime assert and the allocator worked fine 🤷

Originally, I had thought this meant "built for Release fast, multi-threading supported", but now I think it means "built for ReleaseFast and multi-threading".
(I think the comma before the "with multi-threading" is technically grammatically incorrect in that case, but anyway 🤷♂️)
