The number of arguments on Builder::bind_pattern are getting out of hand

[oli-obk]

We should clean up bind_pattern and other methods on the same type. I don't know yet how, we should first investigate the call sites and see if there are common patterns that can be merged:

• two option args that are always both Some or both None
• Maybe add an argument struct that defaults most fields
• consider splitting it into multiple methods and then building named methods with fewer args around those split methods
