I personally strongly oppose removing Feet, FMC, and 7x7, and don’t see a really good argument for removing clock even though I don’t especially enjoy it myself.Amen to that. Some events would, in my opinion, honestly be better off removed.
(The ones I'm thinking of are 3WF, 3FMC, 7x7, or maybe Clock)
If we were seriously considering adding events I don’t believe that clock has enough similarity to current events to recommend it, and hardware is definitely an issue, but absent a strong argument for change I believe tradition is a strong enough argument to keep it.
7x7 doesn’t add as much variation as 6x6, but with better hardware, fewer possible parities, and more room for error in a longer solve it is perhaps a more accessible event for beginners than 6x6.
FMC is the (almost) no holds barred pursuit of absolute efficiency in solving. It is different than other events, I don’t especially enjoy it myself, and single world records are getting a bit silly, but it definitely deserves a place in the WCA.
Feet holds a place between OH and FMC in how much it relatively rewards good turning speed vs. efficiency. Furthermore, it’s lack of popularity means that competitive times are accessible to cubers that might not have he natural talent or thousands of hours of practice time necessary to achieve competitive times on other puzzles.
