Lets talk about mixing levels (again)

Some years ago we had lots of discussions about proper mixing levels in the digital domain – with mixed (sic!) results, IIRC. Meanwhile, more and more influencers are claiming that targeting -18dBFS with a VU meter readout is the “digital audio sweet spot” and the way forward in terms of plugin gain staging. In practise that would imply mixing digital peak levels at around 0dBFS again but maybe I’ve missed something during my absence in recent years. So, to what mixing levels are you up to in your DAW today?
