Nobody has yet been able to put forth a solid argument on why an August - May season is so utterly crucial that it could potentially force the shortening of future seasons to fit that traditional time frame.
There are obvious reasons for the calendar:
- Aligning with other major European leagues makes sense for the transfer windows and when teams would be willing to sell their players.
- UEFA competitions also need us to start at the same time in regards to CL and EL qualifiers.
- We’d have to re-sign all PL contracts otherwise players would leave before a season is over. Same for staff.
- Gives us sufficient time in between a season ending and a WC/EC starting.
You mention WC 2022 being out of sync which is true but I’ve read reports of how they’ll sort that out where it changes things a matter of weeks - due to most leagues having a winter break - whereas this would be changing things for a matter of months. Also TV deals would need to change due to their end date whilst we’d have to see what impact it would have on the deals when only one major league is being played of a weekend and only a handful max of the matches are shown.
I also suspect fans, those keeping this thing all in existence with their support, revenue etc. would probably - outside of ones like yourself - not really want their schedules changing. Some families combine school holidays with away pre-season games etc. which wouldn’t happen anymore.
