Words like this have a long history in Chihuahua, Tom. At one time I was swayed by reasoning similar to yours, and willing to accept any word ending in
S which had a usage where there was no corresponding singular word, even where there were other usages as a conventional plural. At this time I agreed to accept
hives (the disease) and
divers (several). However, subsequent discussion about words for items of apparel caused me to change my mind. (As a result,
hives and
divers were not added to the list.) A search on "plurals" should lead you to several threads discussing these issues. Incidentally,
threads is another one of those words, as an informal term for clothes. When someone says, "Nice threads!" you don't reply, "Thanks. Which thread do you like best?"
The approach I've been following for some time is to look at each case individually, and try to weigh up the relative familiarity of different meanings of a word. I conclude that most people seeing
hives would think of structures housing bees, and most people seeing
divers would think of those who engage in various aquatic pursuits.
Pants is probably a borderline case, but as T says, I eventually gave in to relentless pressure.
I did actually give
taps as an example, in
this post, of words that I felt should not be accepted. A look in the dictionary reveals that
tap has a surprising number of meanings, all of which can have an
S appended to make a plural or verb inflection. I'm sure most people seeing the word
taps would think of taps on the shoulder, dripping taps, phone taps, etc. Especially people outside the US, since it seems the military usage is specific to that country, but even in America, I think the military sense is strongly outweighed by other senses. (The
Corpus of Contemporary American English has over 1600 occurrences of
taps. I scanned the first 100, and there seemed to be only 2 instances of the military meaning.)
I can see that allowing
pants and not
taps will seem inconsistent to some players, but I fear that more people would perceive inconsistency if I allowed words like
taps. Players who don't know of the military signal, or just don't think of it, will be wondering why
taps is permitted while, say,
pats is not.
