Yes, you are probably right, now that I think about it. I actually just installed mine.If the check valve in the adaptor, and the filter's ADBV are both working right, then punching a hole in the fiter dome probably won't drain the filter. It drains on my Tacoma because there is no check valve on the center tube.
You could certainly try it to verify, but I doubt it will work when the adaptor is installed.
I also think clear flood mode is still a great alternative as well,
Having to do that every time you start the car would be a big pain, not to mention kinda embarrassing when your engine is turning over a bunch of times and not starting.
