Spring Security 7 removed AntPathRequestMatcher and MvcRequestMatcher in favor of PathPatternRequestMatcher.

As part of this, request-matcher="path" will be supported in 7 as of #18737, allowing applications using request-matcher="mvc" or request-matcher="ant" to migrate.

However, it would be helpful if 6.5 also supported this so that applications could migrate before upgrading their dependencies.

The benefit of this should be weighed carefully against the impact of changing a maintenance branch as it may be a non-trivial amount of code to add to 6.5.x.
