It would upset me if either of those were primary activities of the lw group in the place I was in.

There is a rather enormous difference between things I care whether lwers do and things I care whether lw does. Some lwers somewhere having rituals doesn't bother me, every lw group deciding rituals are a good idea and adopting them would. I don't think this is actually a big risk but I think it's worth pointing out especially since the context is the especially influential NYLW group.

Also, the less strict something is the less I care whether it's a ritualized regular occurrence. I would much rather come to a song night than to a night for the same specific songs each time, and I would basically never go to catan night.
