Yeah with L3 I think it's always better to treat links as separate entities to gain full control over what flows through which link.
I rather trust IGP+FIB than LACP to decide whether link is operational again.
And it's not like one needs to conserve the number of IPs or adjacencies cause IGP is running out of steam.
