I'm not naive and I know that we aren't in true wilderness and there are differences that remain.  Obviously I'm not referring to the things that are already there (Logging artifacts are cool and part of the heritage of the park.  Same with pictos, portages, old cars and bridge remains) 

Personally, I am okay with the following:

1)  One inukshuk here and there.  Fine, kids, I get it.  It's what you do.  But 5 or more strewn about a campsite?  They won't last by the time I'm done with the site.

2)  One small fire-grate hiding in the juniper bush behind the tent sites.  Not a big deal - I may even use it to bake my foil wrapped LT.  The other 4 leaned up against the quarry of rocks used for a fire-pit will be packed out by yours truly.

3)  A small to medium size fire-pit.  I don't understand the chimney fire-pits.  Seriously, a few rocks will suffice but if it's higher than my knees, it usually comes down.

4)  Some garbage in the firepit.  Not a big deal to me and I have no problem picking out a few foil wrappers or tobacco cans and packing them out.  Easy fix.

I am not okay with;

1)  TP/human waste, homemade latrines.  I think we can all agree on this.

2)  Log benches.  Sorry, pack in a decent camp-chair please.

3)  Chimney fireplaces.

4)  Plywood tables and nails used to construct them.  I typically let the park know but most of them are still standing even after notification.

5)  Half burnt, 10 foot logs sitting along the fire area.  I'm guessing this is the result of a group too lazy to gather firewood and just started burning benches??  It's what it looks like anyway.

As to the BW comparison . . . I don't disparage the BW or those who use it.  I'm glad its there and glad people use it.  Heck, I'll even do a 2-3 day trip through there on a whim.  But, there is no question as to the difference in "wilderness" experience between areas of the 2 parks.  A campsite on Lake Three and a campsite on Cirrus are worlds apart in all ways and I hope it stays that way.  (The unfortunate part is that the difference between a Lake 3 campsite and anything 15 miles north of Prairie Portage is not that different anymore.)   :-/
