Wrong "Resent-From:" because of $from not set.
A symptom of the more general problem that for (pre)historical
reasons many people keep using "my_hdr From:" where they should not:
Anywhere outside of send-hooks.

That is a pretty common situation. Nothing there seems to require
an arbitrary fixed envelope sender different from header. Or what?

Automatic header to envelope link: Whatever means is used to set
sender in header ($from, $reverse_name, "my_hdr From:", $edit_headers,
compose:<edit-from>, in macros, hooks, statically, or manually), the
envelope will always be coherant.
The -f in $sendmail trick, or the new $envelope_from_address, are
usefull *only* when something in your mail setup requires an envelope
sender address that is both not the same as header, and not the local
user@hostname. Rare case.
· Most people need same header and envelope: $envelope_from=yes
· A notable minority needs user@hostname (later masqueraded by some
outgoing MTA): $envelope_from=no
· Other needs do exist, but are marginal. The (3?) guys in this case
generally knows what he must configure.
I don't know your constraints: If you really are in the last case,
happily using -f/$efa, then fine. But I object to your "dangerous"
advice, unappropriate for the OP and for the vast majority.
