Bathroom Wall Panels

Just a quickie if i may?

We're social housing residents and a quote from a contractor has just been approved to remove the tiles in our bathroom with walk-in shower, and install wall panels.
Housing didn't want to retile.

These are the panels the contractor will be installing -

Question is can a shelf and a cabinet be hung to these panels?

Would plug and screw like they are now to the tiles be ok?

And finally if the shelf or cabinet were to be removed in the future, is it the same as with tiles, just silicone the holes?

Thanks
