I don't think this patch is likely to succeed if we throw in more ideas
in every round.
I think we have or are approaching agreement on moving recovery.conf
into postgresql.conf, making the settings reloadable, and adding signal
(formerly trigger) files to trigger recovery or standby. I think that
is a useful change, but it's already big enough and needs extensive
reviewing and testing.
All the other stuff, such as regrouping the recovery parameters,
removing the hot_standby setting, renaming the primary_* parameters,
making the directory of the signal files configurable, should be
separate patches that should be discussed separately. I think the
arguments for these latter changes are weaker, and tactically I would
focus on getting the recovery.conf move in before thinking about all the
other ones.
