The other replies have covered the existing effort to get to 3.12 as 
default, which is a stopgap to 3.13. Generally python@'s procedure is to 
set the default to N-1, where N is the latest upstream CPython release 
branch.

Unlike previous default changes, 3.12 and later's changes have become 
far more intrusive, specifically deprecations and removals of certain 
components that nearly every package has (historically) relied on. The 
greater Python package ecosystem has also not been the most timely to 
act upon those changes let alone receive the information of them happening.

The main problem for us in ports is that setting a lower flavour bound 
that is higher than the default is broken. This is because the flavour 
corresponding to the default will not exist, which causes 
poudriere-bulk(8) to abort immediately. The workaround is to set the 
lower bound to the current default, but set BROKEN on every flavour 
except for 3.14 (and soon 3.14t).

Which dependencies have an upper flavour bound to < 3.14?
