Quite right. I thought of that.
It's feasible - there are, at a guess, a dozen places where execution on
an empty cell is performed. These would need to stack a value that T.
or any other side-effect-producing primitive could check.
This proposal could go onto the issues list.

Unfortunately this is simply following the rules by which an empty

execution is intended only to get the shape and type.
You can have the interpreter inform itself that that's what it is doing.
Conceptually, this mechanism should set (then clear) a thread based
"variable" which T. checks, to find if the current thread is inside
this mechanism or not.
