It's in their financial interest.
Consider the hundreds if not thousands of Forms processed. They need to be handled by some similar quantity of government personnel. You are unlikely, in the region, to be able to hire those for less than a cost of $100K per year per each (presuming a $75K pay rate). Replace just ten of those employees with electronic automation and you save a million bucks a year.
As Tom (once again) astutely points out, that gets things done faster, as well as for cheaper--which has been a concern voiced both within and about BAFTE. Who are sensitive to such things, if more to their political masters (who hold the purse strings) than to we mere citizens.
There's a concurrent "gain" in the process, as the e-system can check the entries as you make them. Which saves having to have the bureau check the forms, and then have to get corrections somehow.--which takes both time and personnel, and money.
Getting the end users to do all the work is to the benefit of bureaucrats and staffers, all the better that they only have to work "banker's hours."
The more poignant question might be "Why did it take them decades to implement these changes?"
