Virtualy you have a ceiling on every dive, even on
NDL-dives! In NDL-dives your decompression is done by
ascent speed and limited by the decomodel (most likely
10 meters/minute). And because this value will vary
during ascend it makes sense to add an additional
ceilings like minimum deco or safety stop...

an extra stop to compensate an ascend made too fast and a almost conditionless safety stop are two different things
