fwiw # already means private fields so it's not necessarily a home run

That is true. Of course, that problem is shared with #-based composite literals, too.

And every choice of pipe topic left (^^, @@, #_, etc.) also has problems with visual association. I suppose one could argue that binary ^ is relatively rare.

I still think the formulae in the wiki are pretty good heuristics.

I still think we want to allow for # to be a metacharacter, since we're nearly out of ASCII syntax, so we'd want ## for the topic.

It’s true that we’re almost out of symbols.
@ is also there as a metacharacter, to a limited extent.
I was against ## in that November 2021 incubator call, but I’m less negative toward ## now (because composite literals would probably be much less ubiquitous than record/tuple literals, so there would be much less visual noise with ##).
I still want # most. Its brevity would be so nice.
But ## (and ^^) aren’t terrible. I like #_, @@, and %% less.
