Which is somewhat cringey for a number of out-of-scope reasons.

That doesn't address whether we should employ $- or a conditional to
find flags to pass to the restarted shell, nor does it address
Arseny's concern about a shell in the "chain" having a nonzero exit
status.  (If use of the PID space is really an issue, the user is
restarting WAY too often.)

I somewhat hesitantly suggest (because I don't have a clear
implementation in mind yet) that perhaps the .zshrc should set a
variable to record that it has been run, and employ some conditional
test(s) to deal with being source'd a second+ time?
