Which still raises the age-old question - who needs 45mp (or 62mp over at Sony)?

You don't need it for web, 4K screens nor for reasonably sized posters (20ish mp is enough here). That leaves image crops as pretty much the only meaningful application.
I thought it was funny how many people are bashing the R6 because it doesn't offer more mp than smartphones.

I do, at least, that is how I think about it.
Basically, for large prints.
I have made large prints of anything from 8 MP to 30 MP, prior to upscaling, but it looks like the sweet spot lies stil a bit higher, although that may well be a moving target (I already found that a 45 MP CCD MF sensor is not the solution, anyway, as my 5D II produced better results ).

In addition, reducing image size from a large file gets rid of some noise if you so like.

Cropping is something I very rarely do, and when i do it, it generally is minimal - goes back to my analog days .

Kind regards, WIm
