I voted no. I thought that the math of epic levels in previous editions quickly got well beyond unwieldy and any sort of feasible within the game world. Particularly with 5e’s attempts to rein in the numbers on a curve, expanding out that high end would have the same issue. Rather, the Epic Boons system works more like the AD&D post-Name Level advancement in certain ways, curtailing growth of numbers in lieu of advancing unique capacities. Although I do agree that there should be some attention paid to how to better play that track (and perhaps more boons offered, including more on the lines of domain rulership and such) — I‘m honestly not interested in that level of play (world-shaking power to me is above tenth level, having grown up gaming in Dragonlance’s maxim of “the gods remove you from the world at 18th level to preserve the balance”), but it fits other styles. Perhaps whatever product finally contains mass combat and domain rules can include something on it (I wouldn’t be adverse to seeing a high-level mega-adventure book which transitions between micro- and macro-scale with these subsystems in play).
