I do have "virtual" packages that have execute set to once, they only 
contain include directives.
All these packages are just used to include the correct release of a 
software that does not support all Windows versions I use.
Sure you can do this within the profiles too.
If you need to maintain multiple revisions of a software other software 
is depending on, it is easier to do this inside of the package 
definition of the software, so you only need to change one file and not 
host, profile and package files.
Some examples below.

'---code start (watch for line wraps)

     <package id="Java" name="Java" revision="2014.10.04"
         reboot="false" priority="10" execute="once">

         <include package-id="JRE6" os="5\.0\.\d{4}"/>
         <include package-id="JRE8">
             <condition>
                 <check type="logical" condition="not">
                     <check type="host" condition="os" value="5\.0\.\d{4}"/>
                 </check>
             </condition>
         </include>
     </package>

     <package
             id="AdobeReader"
             name="Adobe Reader"
             revision="2013.02.16"
             reboot="false"
             priority="10"
             execute="once">

         <!-- install version 9 on Windows 2000 -->
         <include package-id="AdobeReader9" os="5\.0\.\d{4}"/>

         <!-- install version 11 on Windows XP and above -->
         <include package-id="AdobeReader11">
             <condition>
                 <check type="logical" condition="not">
                     <check type="host" condition="os" value="5\.0\.\d{4}"/>
                 </check>
             </condition>
         </include>
     </package>

     <package
