Note that is exactly what I have suggested when using "standby" mode
from pg_ctl.
But you already know that, since you said "If it's possible to run a
replica without having a recovery.conf file,
then I'm fine with your solution", and I already confirmed back to you
that would be possible.

See above. Calling it a compromise in this way implies nobody has been
given exactly what they ask for, but that is not the case.

Please read my proposal again. I'll be happy to answer questions if
you have any.
