Virtually all GCs are known to be horrible at managing scarce resources
(including memory itself).
The destructor can be a crutch, but it's not good to leave open resources
when the user of your code has not cleaned them up manually.
I can see no reason to disallow destruction from cleaning up resources
that nobody else has managed to clean up.
The largest problem with D destructors comes from trying to clean up D
objects in destructors of structs, that you never expected to be done via
the GC.
Cleaning up files and malloc'd memory is not an issue.
