That is exactly the reason. and is the main difference between Apache mode and Nginx mode in W3TC. The plugin needs to be able to create URL rewriting rules on the fly, and nginx gives them no sane way to do it.
Htaccess sucks for various reasons, but most of the suck can be worked around.

Yes, htaccess is ugly but at least a server operator can restrict the users from pwning the machine and only allow rewrite-configs.
