Yes. Also others on the dev list will comment.

The REST API can produce JSON. You just need to set the request header.

You do not need to do this. Just ask for JSON and you will get JSON. For 
example, /policy can return

<?xml version="1.0" encoding="UTF-8"?>
<ts-rest:policyDescription 
xmlns:ts-rest="http://ns.taverna.org.uk/2010/xml/server/rest/" 
xmlns:admin="http://ns.taverna.org.uk/2010/xml/server/admin/" 
xmlns:feed="http://ns.taverna.org.uk/2010/xml/server/feed/" 
xmlns:port="http://ns.taverna.org.uk/2010/port/" 
xmlns:ts="http://ns.taverna.org.uk/2010/xml/server/" 
xmlns:ts-soap="http://ns.taverna.org.uk/2010/xml/server/soap/" 
xmlns:xlink="http://www.w3.org/1999/xlink" ts:serverVersion="2.4.4" 
ts:serverRevision="unknownRevision (branch: 
tags/server-2.4.4/server-webapp)" 
ts:serverBuildTimestamp="2013-12-16T13:53:23+0000">
    <ts-rest:runLimit xlink:href="https://theserver/rest/policy/runLimit" />
    <ts-rest:permittedWorkflows

    <ts-rest:permittedListenerTypes

    <ts-rest:enabledNotificationFabrics 
xlink:href="https://theserver/rest/policy/enabledNotificationFabrics" />
</ts-rest:policyDescription>

or

{
   "policyDescription": {
     "@serverVersion": "2.4.4",

I would _strongly_ recommend using Jira instead.
