Please don't start any deprecation process. This requires certain
consultation within my company. Rest assured that everyone's opinion will
be taken into account while doing consiltation.
The idea of having a deprecation process is precisely to
allow time for people like to provide feedback before any
deletion takes place. So this is not a reason to delay
starting of deprecation.
The process lasts for 2 releases before we delete anything:

When we start the clock now, it is deprecated when 5.0 releases
in April 2020, and still deprecated with 5.1 in August 2020.
The code won't be deleted until Sep 2020 when 5.2 dev cycle opens,
and there's still time to undelete it right up until the 5.2 feature
freeze in late Oct 2020. That's 11 months away, which is plenty of
time for feedback IMHO.
