No. A historical announcement describes a programme event, not your application’s progress or a personal immigration deadline.
Replace launch dates with case milestones
Ask for the current official application sequence and identify which steps you have actually completed. Recheck any advertised turnaround against availability and your circumstances. Plan travel or a move only with advice on the status you will hold, rather than on an old forecast in a proposal.
Distinguish four different clocks that a proposal tends to merge: when the applicant can submit, how long a decision takes, when any payment is due, and when the family could actually relocate. Ask for each separately and in writing. Treat any stated processing time as an estimate unless it appears in current official materials, and note that estimates published for one programme do not transfer to another.
Where a schedule depends on the programme reaching a particular stage of implementation, that dependency should be stated rather than presented as a delay in the applicant’s own case. Make irreversible personal decisions — a resignation, a property sale, a school withdrawal — against status the applicant actually holds, not against a projected date. If an adviser cannot explain what happens to the timetable if the programme’s terms change, that is itself information about how much weight the timetable can bear.
