Yup

I think that any decision to support FTP should be separated from the
decision about what HTTP server to use.

I made a mistake several years ago when I decided to (have Amos)
implement FTP over ZPublisher. The Zope publisher is a CGI-inspired
HTTP-based and thus stateless API. It is a poor fit for FTP and I
overgeneralized.

I don't know what the current Zope 3 FTP integration is like.  If I were
do do this today, I would design a Python-based FTP server with hooks
that one could deploy on top of a ZODB app.  Then if I wanted an FTP server
as well as an HTTP server, I would simply use separate processes.
