I also completely dislike the idea of adding experimental gismu, at least until baseline is finally lifted (and even then, in most cases), except in cases where absolutely necessary (and sarni and salni ain't them). In any case, your (lorxus'?) original argument is at best specious, because just like in languages such as English, the default for tersilna is zo'e, which means, in normal conversation, when you say "ko dunda lo silna mi" or "lo rectu cu se vrusi lo ka silna", your listener is going to assume "...be fi lo sodna be lo ratni be li papa kuku joi lo kliru be lo ratni be li paze", unless you specify otherwise, or you are working in lab with e.g. radium salts, or your listener is insane.
There is really no need for people to always try to complicate matters by multiplying gismu (or using overly precise lujvo or fu'ivla) when not necessary,
