Owens Corning R11 between a few basement joists above washer and dryer

I have some R11 Owens Corning fiberglass insulation above washer and dryer EXPOSED and stapled in between the joists. The house was built in 1971, so I have no idea when it was put there.

I happened to read the lettering and it said "Foil facing should not be left exposed" or something.

Is it a problem leaving the foil face exposed between the unfinished basement joists?

It looks old and of course some is dirty looking. Is there something better and more modern to use or is it a waste of time?

I know nothing about insulation.

If it's exposed then the fibers can get out, it;s not intended to be exposed to the occupied environment and best if sealed off.

More to do with fire codes then fibers getting out.
There should have been 5/8 fire code sheetrock on that ceiling.
Every been to a dryer fire?

Never seen fire rated drywall installed in a laundry room around these parts!

If it was on the ceiling it was probably an attempt to reduce the w/d noise.
The caution to not leave the surface exposed might have wanted it behind a rigid air barrier so it can perform as a vapor barrier. Long explanation but in the ceiling above your w/d does not apply.

Cover or leave as you wish.
