Because one important interactive use of 'recenter' is to redraw the
screen to eliminate display corruptions due to all kinds of unrelated
messages being dumped on the console.  When this variable and the
related feature was introduced, RMS explicitly asked not to change the
then default behavior on TTY's, see

If you don't care about fixing corrupted display on TTYs (or never
experienced that), you can safely change it to nil.

Why does it have to change by default?  I generally find arguments
about default values to be waste of time and energy, since anyone who
doesn't like the default can change it for them.
