re:A lens that only fits on plastic lens mount

[mike wilson]

Seth says:
My guess is that under similar use, the metal lens mounts will
last substantially longer than plastic ones.

I reply:

Agreed.  Looks better, too, in most "classic" applications.  But
when do you know if it is worn out?

Another scenario:  You drop your camera and lens.  Both mounts
are metal and both are damaged because they are of approximately
equal strength, which is exceeded by the accident.  But if one
was designed to fail under such extreme conditions, and that
part was extremely cheap to replace, is that a "better" part?
Should the "fail" part be on the lens?
