Kevin, I cannot speak to your specific use case, but regarding this:

This could be a problem depending on how large your FreeIPA replication farm is, and whether you have safeguards to keep the enrollments under control.   For example we had a user with an auto-scaling group which was supposed to spin up 100 or so instances.   A flaw in their code caused the instances to die quickly, which the auto-scaling group would try to replace.    Left alone, we ended up with 50,000 unused host entries in ipa.   As it was happening, these new entries had to replicate across our very large ipa farm causing slow performance & service interruptions far far away from the faulty auto-scaling group.
