1. It won't allow you to do frontend processing (ssi, charset
conversions, xslt, adding headers/footers via addition_module,
substitutions via sub_module; not sure how this will affect cache
if used).

2. If other servers used as backends (not nginx), and gzipping on
them may be a bad idea since nginx usually faster and more
efficient.

So general practice is to avoid gzipping on backends and do this
on nginx frontend.
