The restriction covers what it says; there isn't anything implied. An ATC
contains neither an abort_statement (check the grammar) nor a call to
Abort_Task.

It seems like there should be a way to eliminate ATC as well. Ravenscar uses
No_Select_Statements (which will be in Ada 0Y), but that is too broad a
brush if you just want to get rid of aborts.

You probably should send a bug report to ACT (about the missing Abort_Task)
and a comment to Ada-Comment (about ATC).
