People on non-recent perls are only going to be surprised if they
1) use the given ($@) construct,
2) upgrade to 5.26.0 (assuming this proposal makes it to 5.26.0), and
3) skip all the intermediate perls that do warn.
But people skipping over several versions with an upgrade are always
at a risk of getting surprised. No many how many cycles we have a
"deprecated" (or in this case a retro active "experimental") warning,
it's always theoretical possible someone upgrades from perl that did
not have this warning. That's not something specific to a change to
~~ and/or given.
The only defense against that is to never ever change anything.
