Making each into a power is an extreme response, though, when there is a simpler answer. As I mentioned above, Savage Worlds provides a single Trick mechanic to represent a wide variety of these types of maneuvers. This one mechanic can be balanced for effectiveness, while being functional for a wide variety of things the PCs attempt.
D&DN, to a large extent, already has this built in due to bounded accuracy and a list of conditions. The smaller bonuses applied to the full range of ability scores means that the chance of any trick succeeding is going to differ by enemy, often opening up different opportunities in each fight. A lack of feat chains makes these options available to anybody. Finally, the list of conditions makes it easy to apply the results of a trick.
