I'm seriously considering it. I have several formula installed with options and I really don't want to have to go through every formula I currently have installed and see if they decided to "bless" the options I need/want.
You can defer that until the option is actually removed. You’ll get an error on the next upgrade. You can then reinstall without the option and decide if that’s still what you want.
If that’s not what you want, you’re free to dig up the formula with the option, and continue to maintain it on your own tap. There’s good documentation for that [1], and there are always people in our forums willing to help if you get stuck [2].
