Use of the word "allowance" in NFHS rule 9-7-3...?

In reality this is probably all a moot point anyway. I think it is highly unlikely that a player would be able to start a slow dribble and back someone down in the lane. This is normally a pretty congested area and if someone were to do this, I would expect that ball would be stolen or swatted away by another defender in pretty short order. Normally I see this type of play occur when player is on the low block, and even then defensive help usually arrives pretty darn quickly so the offensive player doesn't really get to enjoy a slow dribble to the basket. This is a good topic for conversation, but perhaps a different scenario would be more realistic.
