OK, then, can we define a new context property called, e.g.
RevertibleContextProperties, and then call

\override RevertibleContextProperties #'auto-beam-settings #'(end 2 2) =
my-new-autobeam setting

Then, instead of defining a grob property, we could just, as part of
engraver-init.ly, set RevertibleContextProperties = '().

Does this seem better?
