Nope, only two kinds of scripts will be run: old-style scripts with a 
`.sh' extension, and new-style rc.d scripts without extension. So you 
should not run into an trouble with scripts renamed to `.old' or 
`.disabled', except when you got into the habit to *remove* the 
extension to disable the scripts. As stated before: localpkg will not be 
touched and continue to work as before.

See above.

Especially since we can start some ports early in the startup process.

This is simple, but wrong IMHO. Recent experience showed us that only 
because a .sh script has a FreeBSD keyword, it does not qualify as a new 
style script. Basically all current scripts rely on the documented 
behaviour in rc(8). To qualify as a new style script they have to be 
rewritten to work with the new semantics, and installed without an 
extension. Blindly changing documented behaviour will cause a major 
breakage.
