thoughts on setting core.logAllRefUpdates default true for bare repos

It seems to me an accidental push -f would cause some
trouble on a bare repo, and would usually require a bit of
grubbing around among the unreachable commits looking for
the right one.

What would be the downsides (other than some objects hanging
around far longer, i.e., space issues) of setting the config
variable core.logAllRefUpdates to be default true on bare
repos.
