Actually, in my country it is common to size the bundwall height for jetting effects as well. But not to increase the height infinitely, thats not practical. But to adjust the bundwall height and distance from tank to bundwall so that any jet will not exit the bunded area. The typical result is a bund wall that is about 1 to 2m high and a tank to bundwall distance that is half the height of the tank max liquid level.
Ultimately, a bund wall is useless if the liquid can possibly throw itself outside of the containment bund.
Any specific international standards (oil and gas related) referred? I don't mind to follow as long as have solid reference
Various Australian standards relating to the atmospheric pressure storage of hazardous materials (including hydrocarbons and corrosives ) have referred to the leakage crest locus limits for (I'm guessing) probably for 2 decades or more.
Here's a quote from AS 1940-2017 The storage and handling of flammable and combustible liquids, 5.8.3 (Storage in tanks) Design and construction:
(h) The location of a bund relative to the closest tank shall be such that the top inside perimeter of the bund is not inside the crest locus limit specified in Figure 5.2, except where it can be demonstrated that a reduced distance would be appropriate due to viscosity or other considerations.
Refer the shot from one the figures referenced in the quote:

Using this design criteria, the bund wall height is a function of step out distance from the wall of the tank.
I would have thought that Australia is not the only jurisdiction to apply this sort of approach, which is undoubtedly derived from Toricelli's theorem.
