Silly? I disagree. Filters are about more than removing whitespace.
I want the whitespace when I'm developing, because readability and understanding is very important to me. When I use a filter, I can keep the whitespace when I develop and remove it when it really matters - when sending a minimal byte response to a client. At all other times I want to keep it around. All this thrashing to remove it seems sillier to me than filters. The GZip compression filter that I wrote is 119 lines of code, including explicit imports for each class, comments, whitespace, and putting curly braces on their own line. Once I've written it, I can reuse it all over the place by simply adding it to my web.xml.
