I would. The whole point of destructors is to automatically

Yeah, but RAII takes it to the extreme where you create dummy
classes that only consist of constructors/destructors so that
the stack unwinding does all cleanup/closing/freeing without
any try/catch.
This is not necessary in D as we have scope statements.
Before C++ templates that looked verbose and ugly
syntactically, and it is still tedious if you only use the
specific resource in one location. "scope(exit)" is often more
transparent IMO.
I guess this is matter of style and various tradeoff. A very
common operation to rollback probably deserve its own RAII
struct. An uncommon one is better served with scope.
