My understanding is that using "per-prefix-label" will disable a lot of services that depend on vrf-table-label (like FW filters for example)

Anyways, this part is indeed confusing in the documentation and I guess it needs some further lab time.

For Provider Edge Link Protection for BGP Labeled Unicast Paths:
To minimize packet loss when the protected path is down, also use the per-prefix-label statement at the [edit routing-instances instance-name protocols bgp family inet labeled-unicast] hierarchy level. Set this statement on every PE router within the AS containing the protected path.

For Provider Edge Link Protection in Layer 3 VPNs:
Note: The option vrf-table-label must be configured under the [routing-instances instance-name] hierarchy for the routers that have protected PE-CE links. This applies to Junos OS Releases 12.3 through 13.2 inclusive.
