This is the first time I've seen attributes on unittests:

Has this always been supported? I guess it's good practice to
add these
on unittests too, but does people even know about this feature?
And are
there any cons to doing this?
unittest block is effectively just a special function declaration
so all function attributes are applicable and act in a similar
way.
It is an extremely important idiom when you wan't to ensure
specific properties of templated function that may be valid or
not depending on template arguments. For example, function with
output range may be @nogc or not depending if used output range
type triggers GC. But you can mark with @nogc unittest that uses
it with dummy output range to ensure that _nothing else_
allocated.
