Offset wasn't being used before when looking at these two checks. I'm going to assume that was a bug. @Tratcher

Offset isn't important in this check, only the count/length. Offset was checked by ThrowArgumentException.

There was a validation check missing for offset, but count/length is the important part of this check.

I think the nice optimization with this only works for private static ReadOnlySpan<byte> blah => new byte[] {...};

Sorry, I didn't follow - are you recommending changing this to a ReadOnlySpan and calling AsMemory at the callsite?
