Host Profile Export BUG

Describe the bug

The export of an host profile via the vSphere web client or via pyVmomi using the ExportProfile method is not deterministic.

Each time ExportProfile() is called the result is different. The same happens via the vCenter GUI.

Reproduction steps

1. Install pyvmomi via pip3
2. Use vCenter v8.0.2
3. Execute the following script:

from pyVim.connect import SmartConnect
from pyVmomi import vim

si = SmartConnect(host='HOSTNAME', user='USERNAME', pwd='PASSWORD', disableSslCertValidation=True)
content = si.RetrieveContent()
pm = content.hostProfileManager
profile = pm.profile[0]
for _ in range(5):
  print(len(profile.ExportProfile()))

4. The result will be NOT the same, for example this is what happens on my side:

1426335
1426265
1426265
1426265
1426335

5. Go to the vSphere web client, select an host profile, go to Actions -> Export Host Profile -> Save
6. Execute the point 5 many times and observe how the XML changes. For example, in my case sometimes there is the following xml tag inside:
   <string xsi:type="xsd:string">VMkernel.Boot.execInstalledOnly</string>
   and sometimes not.

Expected behavior

We expect to have the same output string each time ExportProfile() is called.
We expect to have the same XML vpf file each time we export the profile from the vSphere web client.

Additional context

No response

Start with the pyVmomi ExportProfile entry point and reproduce the issue against vCenter 8.0.2 using the SmartConnect script in the report. Compare repeated returned profiles and the vSphere web-client exports; done means repeated exports produce identical output, or the issue is shown to originate in vCenter rather than pyVmomi.
