I have bought a new USB-C power supply for a new RPi and the adapter is significantly smaller than the old micro-USB ones, but to my surprise this new power supply also 'suffers' from the 'oversized plug' issue, i.e. it has parts sticking out.
The old supplies have changeable plugs and I used to think that this maybe the cause but the new supply is Australia-only.
What is the reason behind adding the sticking out parts on Raspberry Pi power supplies?
Other plugs in Australia don't have these "wings".
