I believe the reason for this is conservation. Any LIR is entitled to
receiving a /20 up-front (allocation; certainly, assignments from this
need to be made explicitly), so handing out PI /24s where no more space
is needed looks like the better alternative.

Of course, the right to the first allocation might be removed. This has
not happened yet.

There is, however, a difference between routing table pollution (mostly
because of missing or failing aggregation) and small prefixes in the
routing table due to "special" PI service blocks. One should not mix
this.
