I very much appreciate the practical comfort given with the 
"extended" mod type feature and wont miss it.
There are many examples where Ada makes live easier i.e.
where the compiler makes the job instead of the programer,
e.g. the fixed real types when floating point cpu missing,
e.g. the numeric type conversion towards the nearest neighbor
(model number, think of e.g. float2pixel),
and several dozen other new benefits.
This one is a benefit.
