I really appreciate that!
We definitely do need to supply a function for doing this. It's really not trivial to get this right. If we had something like dsubs or dchange then we could make use of it internally as well (e.g. in the ode module).
That is what I had expected would be there - just as you already have for integration in Integral.transform - which is presumably more difficult because you also have the limits to take care of.
