You are confusing the question of fixity (which is what notice is
about) with granularity. It's true that probably no one would bother
to implement the ALHP. However, if computer technologists were handed a
list of leap seconds from now until 2015, and told "Implement these," it
wouldn't matter how many or how few leap seconds there were. But since
you astronomers insist on a fixed maximum for |DUT1|, no such table
can exist.
The proposal is this: look at the trends, take your best shot at
working out a leap-year schedule for 10 years in the future, and then
live with it.
