Steam specifically designed the system to make it easier for developers to handle pricing for multiple regions, and in their SteamWorks documentation on pricing for developers in the Regional Pricing Recommendations section they say:

“All of these factors have driven us towards the commitment to refresh these price suggestions on a much more regular cadence, so that we’re keeping pace with economic changes over time.”

yet their suggested pricing has not changed since the program was introduced in 2022. If they don’t want to commit to keeping the pricing up to date, as they themselves promise, then retire the program and let publishers set the price themselves on every game.
