For future-proofing, better to buy Panasonic lenses even with Olympus body?

I realize that Olympus cameras have IBIS so lens stabilization isn't strictly necessary, but if one isn't sure that one will stay with Olympus (Panasonic does make some nice bodies), would it be safer to stick to Panasonic lenses that have lens stabilization so that you can still use your lenses if you ever decide to switch over?
