Attribute "secure" not migrated to Undertow subsystem

We need to migrate the following EAP 6 configuration from the web subsystem:

<subsystem xmlns="urn:jboss:domain:web:2.1" default-virtual-server="default-host" native="false">

<connector name="http" protocol="HTTP/1.1" scheme="http" socket-binding="http"/>
<connector name="httpconfidential" protocol="HTTP/1.1" scheme="http" socket-binding="httpsecure" secure="true" enabled="true"/>

<virtual-server name="default-host" enable-welcome-root="true">
<alias name="localhost"/>
<alias name="example.com"/>
</virtual-server>
</subsystem>

This configuration uses the *secure="true" * attribute to support the transport-guarantee to CONFIDENTIAL which is required by our applications. (We don't use https in EAP which is configured only on the Apache Web server that serves request to EAP 6)

The configuration has been migrated into EAP 7.0.0 Alpha using the CLI /subsystem=web:migrate command. Although no warnings are shown, the resulting configuration does not contain the attribute "secure" :

<subsystem xmlns="urn:jboss:domain:undertow:3.0">
<buffer-cache name="default"/>
<server name="default-server">
<http-listener name="http" socket-binding="http"/>
<http-listener name="httpconfidential" socket-binding="httpsecure"/>
<host name="default-host" alias="localhost, example.com">
<location name="/" handler="welcome-content"/>
</host>
</server>
<servlet-container name="default">
<jsp-config/>
</servlet-container>
<handlers>
<file name="welcome-content" path="${jboss.home.dir}/welcome-content"/>
</handlers>
</subsystem>

Is there any plan to provide backward compatiblity for the secure attribute in EAP 7 ?
