I don't see any technical problems for existing mechanisms to deal with
leap seconds until we need more than one leap second per day. On the
contrary, weekly or daily leap seconds will simply make it less
necessary to insert test leap seconds when you design clock drivers, as
the real thing will happen often enough. I have yet to see any piece of
code or message format that assumes about the time of a leap second
anything other than that it happens at the end of a UTC day.

Humanity is facing far more interesting challenges before the need for
intruducing 23:59:61 becomes acute in a few ten thousand years from now,
(including, hopefully, the abolishion of our archaic base-60 time notation).
