Just 1 indent vs arbitrary number of indents depending on operator 
priority/ast nesting. Seems like "simpler" is appropriate.

Okay, how about ruby-indent-operator-continuation?

Or ruby-indent-binary-op-continuation. Which would include all binary 
operators and method calls. *shrug* We could also split off the method 
call indentation to a separate option too.

That might be a good adjective (if we take it to mean, not aligned to 
the closest parent AST node), but something else to narrow down the 
scope is needed in the name. ruby-operator-unaligned-indent?

ruby-operator-shallow-indent?

Beginning of statement, I guess?
