Classic bits - forgotten?

There are some really classic D&D style roleplay tropes. I am wondering which of these are still in play these days, considering some resistance to the "spike the doors of the dungeon room, so we can take an 8 hour rest" maneuver performed by my current Castles and Crusades group.

• Spiking doors.
• Carrying rations (to eat, and to throw down a corridor to lure monsters).
• 10' pole.
• High Hard Boots.
• Continual light cast on a small object to be thrown into a room.
• Henchmen.
• Mapping.
• Characters having a "last will and testament".
• Fearing oozes, slimes, and jellies.
• If you didn't bring it into the dungeon with you, DON'T EAT IT.
• Elves make the best thieves (secret door spotting).
• 2 Fighters (or fighter-types) for every other party member.
• Attracting followers and building a stronghold.
• 50' of silk rope (hemp weighs too much).
• Small cage with a songbird in it (warns of gas problems).
• Caltrops.
• Humans in the rear, with polearms, fighting over shorter demi-humans in the front.
• Hooded lantern or bullseye lantern - it makes a difference.
• Flasks of oil.
• Flasks of holy water.
• Flasks of acid.
• Extra bowstrings.
• Hammer and pitons - because you never know.
• At least one person in the party should wear wolfsbane.
• Someone should carry garlic.
• Pool extra money at the start for thieves tools and holy symbols.
• First level fighters shouldn't balk at wearing that better armor the dead orc has on.
• Somebody has a pouch of copper pieces, to toss on the floor and distract the kobolds.
• Secret phrase to check for Doppleganger infiltration.
