[bbhtt]

from lxml import etree

# curl -sL https://hub.flathub.org/repo/appstream/x86_64/appstream.xml.gz | gunzip -- > appstream.xml
components = etree.parse("appstream.xml").getroot()
for component in components.iterchildren(tag="component"):
   if component.attrib.get("type") not in ("desktop","desktop-application"):
        continue
   flatpak_id = component.find("bundle").text.split("/")[1]
   launchable = component.xpath("launchable[@type='desktop-id']/text()")
   if launchable:
      l_value = str(launchable[0])
      if l_value != flatpak_id + ".desktop":
        print(flatpak_id)

These 5 are need to be notified, some of them have multiple launchables defined which is discouraged in the spec.
