I understand that. But the rationale you gave for having a default

was to be able to disable default construction.
RAII or construction based on template parameters.
I know what default constructors are used for in C++. That wasn't what
I asked, though. I asked for compelling rationale.
I have bunch of code that goes like :
auto oldVar = var;
scope(exit) var = oldVar;
This is begging for a RAII solution where I pass var as template
parameter but would require default constructor.
No need for a default constructor. You pass the current value as a
constructor parameter.
