This mechanical loop looks like this: WB and BG overlap with put into exile triggers BG and GU overlap with late game mana cards GU and UW overlap with wanting low mana value creatures on the board RW and UW overlap in wanting creatures that werent cast RB and RW overlap with wanting to cast artifacts RB and UB overlap with wanting noncreature permanent cards to enter your graveyard UB and UR overlap in rewarding bouncing your own creatures UR and RG overlap in protecting attackers RG and GW overlap in wanting very large creatures GW and WB overlap in wanting to not cast spells This set of overlaps doesnt want a lot of cards to represent it

All this is to say, while people with big Reserved List collections will lose some value if the foil loophole is reinstated on the Gaea's Cradles and Gilded Drakes of the world, the impact is likely overblown, as the most expensive cards on the Reserved List are expensive because they are extremely rare and collectible, not because they haven't been reprinted
Reprint value is decent, too
I mean, what more could you possibly want from a commander
The game continues to evolve and presents new mechanics
