Not just because there's too much to load, but because "page caching" and
"fragment caching" are two utterly different things, and you can't suddenly
make them relevant to each other by saying "page fragment caching",
especially not in the context of advanced-cache.php. Ne'er the twain shall
meet, etc.

I've said it before, but I'll say it again, because you keep missing the
point: Fragment caching is useful way up high in the application stack,
with plugins and themes. There is no fragment caching when you're working
at the level of page-or-no-page (i.e. advanced-cache.php). It's just not
relevant or useful. Sure, you could do some dirty tricks to pull apart the
page at the end of your output buffer handler, without any
application-level context besides the raw HTML, but... whaaaaat?

I know a fair bit about WordPress performance, and I don't like it when
someone is wrong on the Internet. Repeatedly. Where others might read it.
