Well periodic updates in on by default in xboard! It tells you
during analysis which root move the engine is thinking about.
This is very useful information and I cannot see why one would
want to disable it.

It would be useful if this feature were also available during normal
search but the xboard protocol does not allow for this
(in contrast to the UCI protocol).

Well it definitely still exists in xboard 4.4.0beta. Has it been disabled
since then?

I often prefer the analysis window since it takes very little screen space.
If you just want the PV then you are not interested in all the information
provided by the engine output window.

Just start an analysis with periodic updates enabled (the default!) and
an engine supporting them (e.g. polyglot). Look at the
analysis window and see the PV being blanked out regularly.
