shu: DetachArrayBuffer only allows an AB, not a SAB - is there no need/way for the web to detach SABs? if so, how do they do it in the spec? should DetachArrayBuffer allow SABs also, just like IsDetachedBuffer does?

i do see that structuredClone/MessageChannel in node doesn't allow transferring SABs

SABs cannot be detached

transferirng a SAB doesn't detach it

that is in fact the point of SABs
