I agree that client access to ports below 1024 usually requires more privileges 
and that’s generally safer than allowing any client port.

That would work.

The policy of Let’s Encrypt Certificate Authority, however, is very important!  
 I also would very much like that CA to allow client-defined callback ports 
below 1024.
