httpd - Support sending 451 status from RewriteRule

I want to be able to send a http status 451 from httpd using a RewriteRule
More info regarding http status 451: https://en.wikipedia.org/wiki/HTTP_451

Current version installed:
httpd.x86_64 2.4.6-40.el7 @rhel-x86_64-server-7

httpd 2.x patch:
https://bz.apache.org/bugzilla/show_bug.cgi?id=58985
Yehuda Katz has provided a patch for 2.4

When can I expect this patch to be included in the httpd (RHEL7 repo)?
