It's always been that way on Macbooks. It's also simplified with USB 4, which means the newest Macbooks just support everything under Thunderbolt / USB 4 on every port. Older Macbooks may have had some Display Port shenanigans because of differences between DP 1.2 and DP 1.4 and whether it was over Thunderbolt 3 or USB 3.1, but all modes were basically supported.
Any port on any Macbook with USB-C can be used as the charging port, which is a big deal all on its own compared to most non-Macbook laptops that use USB-C charging.
