Roaming through the Roman Tragedies - is this the ultimate in immersive theatre?

Got this email yesterday ahead of our visit to see Ivo Van Hove's Roman Tragedies at the Barbican next month:

We look forward to welcoming you in March for Toneelgroep Amsterdam’s Roman Tragedies at the Barbican. For those not familiar with the format of the show, after the first half an hour of the performance you will be allowed to move freely around the auditorium and stage until the final 75 minutes of the performance when you will be asked to return to sitting in the auditorium. This means that when the performance starts you will have an allocated seat (your seat number can be found on your theatre ticket), but after the Master of Ceremonies invites you to move around, seats in the auditorium will become unallocated for the remainder of the performance.

Refreshments will be available to purchase on stage using cash or contactless payment and you may enter and exit the auditorium whenever you like. Use of mobile phones to access the internet is permissible throughout the performance although we kindly ask you to silence phones and ensure you switch off the flash when taking photos.

We look forward to welcoming you to the Barbican Centre.

Is this the ultimate in immersive theatre? The audience become the extras in the background "shopping" or being a tourist and stopping to take a photo? Curious to see how it works. It could be brilliant, it could be a massive distraction or the British proclivity to avoid embarrassment might prevail and people will stay put.
