You could say that about any indoor activity at this stage; cinemas, theatres, bowling alleys, gyms etc.
Many businesses in this sector won’t survive in their current firm reducing capacity by even 25% for a prolonged period will end most of them. I’d add restaurants and cafes to that list, as we have already seen.
Even a highly profitable (35% EBITDA) and cash generative business like Cineworld will struggle if they have to reduce capacity by 60%.
35% EBITDA is something most businesses dream of, so I can’t see how you can reduce income by even 25% without looking at cutting costs.

I think business support should exist from government as long as capacity restrictions are in place, otherwise businesses failures will continue.
On the other hand, all these companies which require large spaces in which to operate going (or potentially going) bust will add further pressures upon the commercial lease market. A huge chuck of retailer and leisure industry financial commitments go out in rent. The large landlords seem to have been operating* an (illegal) cartel, where there are no alternative spaces available at a reasonable rate. Well, maybe they will now see the writing on the wall and start offering more realistic rents. Of course, commercial rates have to be overhauled too. This means more central and/or local taxation for individuals and taxation of profits.
The other thing which would make a difference is how planning manages out-of-town retail. If they become more restricted and existing sites rezoned over time, this could help drive back operations to more central locations. There are a lot of balls in the air right now. Obviously, the existing paradigm is unsustainable. Here in France, town and city centers are much more vital. Yes, I've noticed more empty spaces because of the epidemic, but generally, far, far fewer than in the UK.

It was a little embarrassing to have my American wife see it. She was quite exited to visit the UK for an extended period (6-7 months), but could not wait to leave (I felt similar). In truth, the city was probably not a lot worse than 10 years ago, but I had forgotten. But I did certainly notice the drop in variety: generally fewer good retailers and the huge rise in fast food and very mediocre cafes. I could not find a single half-decent shoe shop in the city.
All I wanted was some Merrells - I had to buy them online. Ridiculous.
The depression of the high street and city centres started under Thatcher, of course. And no Government since then has attempted to do anything about it - except to let it get worse.
And, like in France, Amazon and the like need to start paying higher taxes.
* I'm speculating, but it would explain why the market has failed to operate as we should expect.
