There's a number of methods that have modern counterparts, recommend using the new ones instead.

For reference, here's where this was added: rspec/rspec-core@7b0d232

Why? I don't see why this requires a cop. It's perfectly fine to have readable code sentences, which is why there's first-class support for aliases in rspec.

Basically because "should" syntax is being removed from RSpec, along with all references to it. See https://github.com/rspec/rspec-core/pull/2864/files#diff-8c60417422cf21f6d3abdc5b63d992eee058c43039601cc0cee1d7111db85420L1133
