As far as I'm concerned, the priority feature for 5.34 should be setting things 
up at the front end to smooth the transition to Perl 7 that follows it.

A key example is that an explicit "use 5.34;" will provide the same semantics 
that would be implicit with Perl 7 later where those would break programs 
lacking a "use" line.

So just as "use 5.12;" or whatever already turns on strict, a "use 5.34;" should 
turn on strict and warnings, and also activate "say" or any other 
non-experimental syntactic features or semantics we conceptually want to have on 
by default, so then "use 5.34;" while being boilerplate is very terse compared 
to the boilerplate to get the same behaviour under previous Perls.

Another example, Perl 5.34 should issue warnings when compiling/running 
something whose behavior may change under Perl 7, such as any file-based code 
lacking an explicit "use" line AND that also would fail strict or uses indirect 
method call syntax or whatever; some of these warnings might be opt-in rather 
than default with a command-line switch or such.
