Still work that way. You have three options. You cloture the person, you move to new business or you wait them out. You still have the option to wait. Nothing has changed.
Waiting means nothing happens. You just wait. If it’s important enough that’s what you do.
You cloture the person
And that essentially isn’t an option at times due to how difficult it is to reach the 60 vote threshold, which means nothing gets done, which means congress is basically useless.
Or you just wait them out. You do nothing until they relent.
Politics sometimes has to be ugly. What you don’t do is make sad excuses as to why things don’t get done. You just shut things down till they go for a vote.
You can’t wait out an indefinite filibuster. And it gets to become indefinite because they don’t actually need to talk at all.
