Thanks for the explanation. I finally understand you initial note.
I was thinking about org-overview mostly because it is the case when
next/previous-line was extremely slow with many overlays jammed between
two subsequent lines.

Currently, `org-flag-region' only removes one SPEC type of overlays:

(remove-overlays from to 'invisible spec)

If we change it to 

(remove-overlays from to 'invisible spec)
(when flag
(remove-overlays from to 'invisible 'org-hide-drawer)
...
)

then all the extra drawer overlays in the flagged region will be
removed. It will require re-creating those extra overlays later if the
region is revealed again though. 

Best,
Ihor
