  I don't think that ever worked.  You can't put a regex into the key field for the attr_filter module.  The matching for keys is done via string equality.

  They're documented as working in proxy.conf.

5.  The attrs file never did what you think it did.

  I've checked the 2.1.6 source.  The matching for keys is done via string equality.  It has *no* regex capability.
