May I ask, in this case, the only way to optimize the extern op is to do it by
hand (with tir intrinsics) right ? For example like topi.sparse.csrmm
implementation, no schedule configs could be associated with it.

The way I can think of is just infer the layout manually from input tensor or
the op with the layout attribute.

Thanks @comaniac, that's what I'm doing right now.
