As per the Process for reviewing classic confinement snaps, for a snap to be granted classic confinement, it must first have a requirement for classic confinement (ie. requires access to arbitrary files / requires to be able to execute arbitrary, user defined executables from the host etc), and it must fit within one of the supported categories for classic confinement.
Can you please provide some more details to help establish if it meets these two requirements? Since it wants to try and profile everything that would seem to indicate that it needs arbitrary access to files from the host - but if it just needs to read them, the it could use the system-backup interface and then look at everything via /var/lib/snapd/hostfs/ - can you provide more info?
