Part of the reason I don't carry such items is that I'm comfortable in my environment and my abilities. In my daypack, I have an AMK bivy (the Gen 1 version), a 2-person heat sheet, and some plastic trash bags. I figure it's enough for a decently comfortable night, when worn over my clothes. I usually have extra clothes (usually a fleece vest at the minimum), so I have insulation there.
If I'm going for a dedicated camping trip, then yeah, I have a tent and sleeping bag.

As a person who does a lot of hiking, I totally agree on this. The environment and my abilities always helps decide which items I carry and which items stay in the car or at home.
On day hikes, the tent and sleeping bags stay home. However extra clothes and some shelter, whether it is the sil-tarp or just a 9x7 sheet of medium weight clear plastic are put into the pack. For the clothing, my standard is the clothes I am wearing plus enough in the pack to keep me warm for 10-15 C overnight drop in temperature without a night fire.
Also when out, I am always on the watch for any improvised shelters that can be used such as overturned tree stumps, rock overhangs etc. These are marked either on our map as we progress or in a small notebook and I always take a photo of the possible shelter and it's immediate area for future reference as seen in the below photos.
Although the photos have been cropped to save bandwidth, all 4 of these improvised shelters are very safe from any danger of surrounding collapse, flood etc. With 10- 15 minutes work to clear spruce up the area and with the addition of the above carried sil-tarp or plastic, our shelters are now large enough for 2 people and offers great protection from the elements. With a small fire burning close by, our odds of comfortably surviving almost any type of weather for multiple nights/days have improved immensely.
Rock and ground overhang. A bit of work to clear out the dirt and level it off a bit, 2 people could lay in there with ease as it is deeper then it looks

Hollowed out cedar stump Once most of the rocks are removed, 2 people could sit /lay in there with leg room to spare)

This cave can also fit 3-4 people and the view is terrific as it looks out into a canyon.

This overturned tree stump /root system is huge and has many great options to rig a comfortable shelter. The dirt is easy to move out and although it is difficult to see in the photo, just behind the slight overhang in front, there is plenty of room to sit completely upright.
