select = pn.widgets.Select(
    value=None,
    options={s or "All": s for s in [None, "A", "B"]},  # This will make All work as None. 
)
select

In Panel 1.4:

In Panel 1.3.8.

An alternative to this is using False, but in my head the None is used as not set value and in my case means all is chosen.

Probably a change in bokeh?
