Either you embrace new technologies or you put some cap and aim for entartainment. WRC is as usual behind the times so it's a big question what they will do in the future.
Having a budget cap is for sure sensible but it's not a thing which would make new manufacturers join and that's been the main issue.

Then it's a business case, otherwise the budget is always open, Hyundai probably spends 10x or 20x to advertise in footbal compared to WRC so if the value rises costs can easily rise too with the current setup. The future of motorsport does not lie in formulas that worked in the past.
This type of thinking about the rules is what I'd prefer as well.
