implement vs render vs support

I think the following sentence would work better if the word "implement" 
were changed to "render". 

http://www.w3.org/WAI/intro/components.php

When One Component is Weak
If an accessibility feature is not implemented in one component, there is 
little motivation for the other components to implement it when it does 
not result in an accessible user experience. For example, developers are 
unlikely to implement an accessibility feature that authoring tools do not 
support and that most browsers or assistive technologies do not implement 
[render] consistently.
