Can we be more precise in deprecation messages of this kind, please?
This warning is not enough for the user to be able to figure out how
to change their existing command line.
I had to look into deprecated.rst, check the git history to see which
commit added the deprecation, then find out how this commit was adjusting
the examples in the tree.
Notably, "-object monitor-hmp" appears to require an "id=" despite
nothing actually caring what that ID is, and the warning message
doesn't say how to determine whether your existing -mon option
should be changed to monitor-hmp or monitor-qmp. The deprecated.rst
docs do say that part, but don't mention the ID bit.
thanks
