Whether regions can be active or not, and whether "active" means that
they limit or extend operations to themselves, or both, might depend on
settings and doesn't necessarily need to be shown all the time.

Such a mode line indicator would need to show which regions are active
when there several and in which way each one of them is active because
there are multiple ways of being active.
Perhaps it could generally show if any region is active and change when
point is within a region to show more of its details.

Another C-spc after starting to mark a region might do to end the
marking.
What would the advantage of hidden regions be? When something is within
a region, it should be highlighted, and when it is no longer
highlighted, it should no longer be within a region.
Are these hidden regions a remnant of technical limitations that made it
advisable not to highlight the selection?
Perhaps region selections could be remembered in registers to make it
easier to re-create them once they were disabled to suppress the
highlighting.

Doesn't that enable transient-mark-mode? If I wanted t-m-m, I could
just leave it enabled to begin with.
I tried with t-m-m disabled, and I don't see what the point of having it
disabled is. Regions are not protected any better, and I'd have to be
stupid to select a region to do something I want to affect the whole
buffer.

It could be accompanied by a region-mode in which nothing can be done to
and with anything outside of the regions.

Isn't is easier to use registers instead?
