You make some very good points. A 22mm hole at a 1' head could flow around 615 GPH if my calculations are correct so there could be conditions where this could allow a lot of water into the boat. I certainly hope to never encounter the conditions that Eric has. One of the primary functions of a boat imo is to keep water on the outside and this seems to me to be a good way to reduce intrusion. I second your concerns about silicones which can be impossible to finish over if they soak into bare wood. Customers have brought boats to us to refinish the interior varnishwork and some where furniture polish was used were impossible to recoat, nothing but fish eyes no matter how much cleaning we did. On the other hand some boats that also had furniture polish used on them were fine to refinish and I never determined which products had silicone or in them and which were safe so I just revarnish when needed.
The varnish on the slider I imagine gives you a nice sealed and fairly hard surface for the wiper to rub on. Does the wiper ever chatter as you raise and lower the slider? I need to reface or replace my door and will go with varnish as well.
Have a safe trip back South.

As Bill R says, I think the weatherstrip is important to keep water out of the boat. If there is ANY gap, all the rain water that hits the surface of the slide will run down the surface of the slide into the boat. It is easy to say "it's only 2mm wide" but it is 750mm long. That is about the same area as a 22 mm round hole. Would you tolerate a 22mm round hole in the side of your cockpit that drained water into the boat? I would not.
An occasional coat of wax on our varnished slide keeps the rubber from sticking to it. We varnished the teak companionway because we much prefer the "look" of well maintained varnish over teak oil--strictly personal preference. With the same maintenance schedule, (and , yes, a bit more work) it holds up well.
If you do decide you prefer varnish, stick with the wax, and avoid the silicone spray and furniture polish containing silicone. Silicone is virtually impossible to remove when it is time to renew the finish, and it can cause you nightmares with the next maintenance coat of varnish "beading up" on the surface. There are ways to get around it, but the best answer (again--with a varnish finish) is to just avoid the silicone.
