One thing I think we don't really know how will factor in yet is transfer time. Before covid stopped it all you could have reasonably short connections in Doha, I had many that were so short I couldn't be bothered to find the lounge and just have a slightly less hectic transfer and waddle on to the next gate at my pace.
Once corona passes and world is returning to normal we will have a route network that initially is very likely to be much more sparse, with longer transfers for many routes. Then lounges may be more desirable. Maybe they are gambling that more will pay for this?
