I'm not defending dialogs or modals, but at least with those (on a larger screen) you have control over what hey cover.

I suspect most users wouldn't even know the bottom sheet is there nor how to bring it up nor how to dismiss it had they brought it up.

The visual context on whatever is underneath is lost once the sheet is brought up.

The user absolutely get forcibly navigated away; their context is shifted to the new layer which is slapped on top of the other layer. I can't count the number of times I either accidentally activated the bottom sheet or used it then got lost.

Bottom sheets are like hamburger menus; they are rugs that UX designers sweep all their baggage underneath.
