Just buy an old one after your current one breaks if you love Magsafe so much. I'm sure many will be willing to sell their old 2015 Macbook pros when one with wireless charging comes out in 2023.
* USB
* Not needing a $25 adapter just to charge my iPhone
* Thunderbolt for my two Thunderbolt displays
Hopefully the used supply of MBP will stay deep for years.

Seriously though the next iPhone/iPad will surely going to use USB-C also and ditch Lightning, which will dramatically simplify the connector situation going on at Apple.
