I'm not sure to get your point?

Are you proposing to match "basic_string" instead of the whole regexp?
I'm in favor of that change as I don't see any counter example or any false positive.

In fact, many checkers are using hasName("basic_string").
I just kept the change as minimal as possible to keep the same semantic and allow matching more cases.

Example from RedundantStringInitCheck.cpp:

  // Match string constructor.
  const auto StringConstructorExpr = expr(anyOf(
      cxxConstructExpr(argumentCountIs(1),
                       hasDeclaration(cxxMethodDecl(hasName("basic_string")))),
