I'd like the option of not printing any port state with a frequency

If you know in advance that there will be many filtered and closed
ports too and you are interested in open ports only, you could try

and use --defeat-rst-ratelimit option.

I know it is not exactly what you want, and the feature you are
talking about *does* make sence - especially when you are scanning for
many TCP and UDP ports in one run which very often results in two
different frequently occuring states (one for TCP and one for UDP).
