We're talking about plugins here. There are no good authoring practices, 
only bad ones and worse ones.

Regarding the three bullets above: For the first one, there are times 
where offering no fallback is fine; for example when to reach the page you 
have to have gone through a mechanism that verifies that you have the 
plugin in the first place, or where the plugin is doing nothing but adding 
something decorative. For the second and third, both are bad, and more or 
less equivalent from the user's perspective; however, they are an 
inevitable result of writing content using a proprietary technology. In 
the case of the second bullet point, the example is specifically of an 
author showing off his Java programming skills, so it makes no sense to 
have any other fallback. The introductory text for the example discusses 
the implications of doing this. For the third bullet point, the text is 
self-explanatory regarding the danger of relying on a plugin -- it is in 
fact that explanation that people are objecting to here.
