They shouldn't feel like punching and kicking are total wastes of time, or know that in a barfight the first thing to do is to break out their swords, because they can't hope to defeat the bar denizens with improvised weapons (because bar denizens tend to be statted as normal monsters, not monsters hamstrung by wielding improvised weapons).Or, given that people should want to use real weapons, they are a roaring success. People only use improvised weapons when circumstances force them to.
That said, I'm not arguing that improvised weapons should be as effective as a full blown weapon, just not as totally ineffective as they are statted as.
Here we are asking, practically begging, for DM/Player communication disasters. You see, the effectiveness of chandelier dropping depends linearly on how cool your DM thinks chandelier dropping is. Either the DM or the player might say:
even a large chandelier, especially merely dropping a modest way under the effect of gravity, unaimed, should be less scary than a strong guy with a short short sword. So damage circa 1d3, with crappy to-hits. On the other hand, that chandelier is still supported by a chain, so don't even start talking until you do 10 or 20 damage to the chain.
If the other one is expecting something like as described up-thread, someone is going to be very unhappy. Worse, a DM could run a module with it, play it straight, and then revert to less effective chandeliers elsewhere.
Playing "DM-may-I" got old really early in 1e. I'd rather not see it return.
Of course if every chandelier, pile of barrels, fireplace etc etc in every encounter is statted up as a useful contributor, then you also don't have those problems. Alternately if the DM has statted up specific ones, and reveals them at the start of the fight, you also are not left guessing.
