Multiple extension points deprecated?

After reading some related threads in this forum I edited my addon.xml to have two extension points like this:

Code:
<extension point="xbmc.python.script" library="select.py">
    <provides>executable</provides>
</extension>
<extension point="xbmc.service" library="service.py" start="[login|startup]" />
</extension>

Unfortunetely with this settings my addon isn’t loaded and and does not even appear listed under available addons. No errors in kodi.log
I thought this was a supported setup or has this feature become deprecated?
